31a9d318a3 Teach tblgen to build permutations of instructions, so that the target author 
doesn't have to specify them manually.  It currently handles associativity,
e.g. knowing that (X*Y)+Z  also matches  X+(Y*Z)  and will be extended in
the future.

It is smart enough to not introduce duplicate patterns or patterns that can
never match.

0231f57a46 Emit an error if instructions or patterns are defined but can never match. 
Currently we check that immediate values live on the RHS of commutative
operators.  Defining ORI like this, for example:

def ORI   : DForm_4<24, (ops GPRC:$dst, GPRC:$src1, u16imm:$src2),
                    "ori $dst, $src1, $src2",
                    [(set GPRC:$dst, (or immZExt16:$src2, GPRC:$src1))]>;

results in:

tblgen: In ORI: Instruction can never match: Immediate values must be on the RHS of commutative operators!

a6d21c974c Implement a complete type inference system for dag patterns, based on the 
constraints defined in the DAG node definitions in the .td files.  This
allows us to infer (and check!) the types for all nodes in the current
ppc .td file.  For example, instead of:

Inst pattern EQV:       (set GPRC:i32:$rT, (xor (xor GPRC:i32:$rA, GPRC:i32:$rB), (imm)<<Predicate_immAllOnes>>))

we now fully infer:

Inst pattern EQV:       (set:void GPRC:i32:$rT, (xor:i32 (xor:i32 GPRC:i32:$rA, GPRC:i32:$rB), (imm:i32)<<Predicate_immAllOnes>>))

from:  (set GPRC:$rT, (not (xor GPRC:$rA, GPRC:$rB)))

b312f4d374 When emitting implicit use/def lists, only emit each unique list once. Though 
LLVM is able to merge identical static const globals, GCC isn't, and this caused
some bloat in the generated data.  This has a marginal effect on PPC, shrinking
the implicit sets from 10->4, but shrinks X86 from 179 to 23, a much bigger
reduction.

This should speed up the register allocator as well by reducing the dcache
footprint for this static data.

c871411c9d Add support for a TODO; instructions in .td files can now have arguments 
printed as part of the opcode.  This allows something like
cmp${cc}ss in the x86 backed to be printed as cmpltss, cmpless, etc.
depending on what the value of $cc is.

c2f7fcfbba Major change to tblgen: instead of resolving values every time a class is 
finished up, only resolve fully when the def is defined.  This allows things
to be changed and all uses to be propagated through.  This implements
TableGen/LazyChange.td and fixes TemplateArgRename.td in the process.

None of the .td files used in LLVM backends are changed at all by this
patch.

078cda0bb3 This is the final big of factoring. This shares cases in suboperand 
differences, which means that identical instructions (after stripping off
the first literal string) do not run any different code at all.  On the X86,
this turns this code:

    switch (MI->getOpcode()) {
    case X86::ADC32mi: printOperand(MI, 4, MVT::i32); break;
    case X86::ADC32mi8: printOperand(MI, 4, MVT::i8); break;
    case X86::ADC32mr: printOperand(MI, 4, MVT::i32); break;
    case X86::ADD32mi: printOperand(MI, 4, MVT::i32); break;
    case X86::ADD32mi8: printOperand(MI, 4, MVT::i8); break;
    case X86::ADD32mr: printOperand(MI, 4, MVT::i32); break;
    case X86::AND32mi: printOperand(MI, 4, MVT::i32); break;
    case X86::AND32mi8: printOperand(MI, 4, MVT::i8); break;
    case X86::AND32mr: printOperand(MI, 4, MVT::i32); break;
    case X86::CMP32mi: printOperand(MI, 4, MVT::i32); break;
    case X86::CMP32mr: printOperand(MI, 4, MVT::i32); break;
    case X86::MOV32mi: printOperand(MI, 4, MVT::i32); break;
    case X86::MOV32mr: printOperand(MI, 4, MVT::i32); break;
    case X86::OR32mi: printOperand(MI, 4, MVT::i32); break;
    case X86::OR32mi8: printOperand(MI, 4, MVT::i8); break;
    case X86::OR32mr: printOperand(MI, 4, MVT::i32); break;
    case X86::ROL32mi: printOperand(MI, 4, MVT::i8); break;
    case X86::ROR32mi: printOperand(MI, 4, MVT::i8); break;
    case X86::SAR32mi: printOperand(MI, 4, MVT::i8); break;
    case X86::SBB32mi: printOperand(MI, 4, MVT::i32); break;
    case X86::SBB32mi8: printOperand(MI, 4, MVT::i8); break;
    case X86::SBB32mr: printOperand(MI, 4, MVT::i32); break;
    case X86::SHL32mi: printOperand(MI, 4, MVT::i8); break;
    case X86::SHLD32mrCL: printOperand(MI, 4, MVT::i32); break;
    case X86::SHR32mi: printOperand(MI, 4, MVT::i8); break;
    case X86::SHRD32mrCL: printOperand(MI, 4, MVT::i32); break;
    case X86::SUB32mi: printOperand(MI, 4, MVT::i32); break;
    case X86::SUB32mi8: printOperand(MI, 4, MVT::i8); break;
    case X86::SUB32mr: printOperand(MI, 4, MVT::i32); break;
    case X86::TEST32mi: printOperand(MI, 4, MVT::i32); break;
    case X86::TEST32mr: printOperand(MI, 4, MVT::i32); break;
    case X86::TEST8mi: printOperand(MI, 4, MVT::i8); break;
    case X86::XCHG32mr: printOperand(MI, 4, MVT::i32); break;
    case X86::XOR32mi: printOperand(MI, 4, MVT::i32); break;
    case X86::XOR32mi8: printOperand(MI, 4, MVT::i8); break;
    case X86::XOR32mr: printOperand(MI, 4, MVT::i32); break;
    }

into this:

    switch (MI->getOpcode()) {
    case X86::ADC32mi:
    case X86::ADC32mr:
    case X86::ADD32mi:
    case X86::ADD32mr:
    case X86::AND32mi:
    case X86::AND32mr:
    case X86::CMP32mi:
    case X86::CMP32mr:
    case X86::MOV32mi:
    case X86::MOV32mr:
    case X86::OR32mi:
    case X86::OR32mr:
    case X86::SBB32mi:
    case X86::SBB32mr:
    case X86::SHLD32mrCL:
    case X86::SHRD32mrCL:
    case X86::SUB32mi:
    case X86::SUB32mr:
    case X86::TEST32mi:
    case X86::TEST32mr:
    case X86::XCHG32mr:
    case X86::XOR32mi:
    case X86::XOR32mr: printOperand(MI, 4, MVT::i32); break;
    case X86::ADC32mi8:
    case X86::ADD32mi8:
    case X86::AND32mi8:
    case X86::OR32mi8:
    case X86::ROL32mi:
    case X86::ROR32mi:
    case X86::SAR32mi:
    case X86::SBB32mi8:
    case X86::SHL32mi:
    case X86::SHR32mi:
    case X86::SUB32mi8:
    case X86::TEST8mi:
    case X86::XOR32mi8: printOperand(MI, 4, MVT::i8); break;
    }

After this, the generated asmwriters look pretty much as though they were
generated by hand.  This shrinks the X86 asmwriter.inc files from 55101->39669
and 55429->39551 bytes each, and PPC from 16766->12859 bytes.

eee6c31449 Implement *even more* factoring. In particular, if all of the instruction 
strings starts out with a constant string, we emit the string first, using
a table lookup (instead of a switch statement).

Because this is usually the opcode portion of the asm string, the differences
between the instructions have now been greatly reduced.  This allows many
more case statements to be grouped together.

This patch also allows instruction cases to be grouped together when the
instruction patterns are exactly identical (common after the opcode string
has been ripped off), and when the differing operand is a MachineInstr
operand that needs to be formatted.

The end result of this is a mean and lean generated AsmPrinter!

a030a47a51 Implement factoring of instruction pattern strings. In particular, instead of 
emitting code like this:

  case PPC::ADD: O  << "add ";  printOperand(MI, 0, MVT::i64); O  << ", ";  prin
tOperand(MI, 1, MVT::i64); O  << ", ";  printOperand(MI, 2, MVT::i64); O  << '\n
'; break;
  case PPC::ADDC: O  << "addc ";  printOperand(MI, 0, MVT::i64); O  << ", ";  pr
intOperand(MI, 1, MVT::i64); O  << ", ";  printOperand(MI, 2, MVT::i64); O  << '
\n'; break;
  case PPC::ADDE: O  << "adde ";  printOperand(MI, 0, MVT::i64); O  << ", ";  pr
intOperand(MI, 1, MVT::i64); O  << ", ";  printOperand(MI, 2, MVT::i64); O  << '
\n'; break;
...

Emit code like this:

  case PPC::ADD:
  case PPC::ADDC:
  case PPC::ADDE:
  ...
    switch (MI->getOpcode()) {
    case PPC::ADD: O << "add "; break;
    case PPC::ADDC: O << "addc "; break;
    case PPC::ADDE: O << "adde "; break;
    ...
    }
    printOperand(MI, 0, MVT::i64);
    O << ", ";
    printOperand(MI, 1, MVT::i64);
    O << ", ";
    printOperand(MI, 2, MVT::i64);
    O << "\n";
    break;

This shrinks the PPC asm writer from 24785->15205 bytes (even though the new
asmwriter has much more whitespace than the old one), and the X86 printers shrink
quite a bit too.  The important implication of this is that GCC no longer hits swap
when building the PPC backend in optimized mode.  Thus this fixes PR448.

67cbd23ad5 Seperate asmstring parsing from emission. This allows the code to be simpler 
and more understandable.  It also allows us to do simple things like fold
consequtive literal strings together.  For example, instead of emitting this
for the X86 backend:

  O  << "adc" << "l" << " ";

we now generate this:

  O << "adcl ";

*whoa* :)

This shrinks the X86 asmwriters from 62729->58267 and 65176->58644 bytes
for the intel/att asm writers respectively.

8dcbaf2f98 Add initial support for list slices. This currently allows you to do stuff 
like this:

def B {
  list<int> X = [10, 20, 30, 4, 1, 1231, 20] [2-4,2,2,0-6];
}

... which isn't particularly useful, but more is to come.
