03637c7200 Keep names even when inlining. This allows us to realize that ADDI is: 
(set GPRC:i32:$rD, (add GPRC:i32:$rA, (imm)<<Predicate_immSExt16>>:$imm))

not:

(set GPRC:i32:$rD, (add GPRC:i32:$rA, (imm)<<Predicate_immSExt16>>))

(we keep the ":$imm")

65c98b6441 Initial cut of the dag isel generator. This is still very much a work in 
progress.  It correctly parses instructions and pattern fragments and glues
together pattern fragments into instructions.

The only code it generates currently is some boilerplate code for things
like the EntryNode.

46a7fdeb66 Implement PR614: 
These changes modify the makefiles so that the output of flex and bison are
placed in the SRC directory, not the OBJ directory. It is intended that they
be checked in as any other LLVM source so that platforms without convenient
access to flex/bison can be compiled. From now on, if you change a .y or
.l file you *must* also commit the generated .cpp and .h files.

9ceee53f9a Emit this: 
static const TargetOperandInfo OperandInfo6[] = { { &PPC32::CRRCRegClass }, { 0 }, };

instead of this:

static const TargetOperandInfo OperandInfo6[] = { { PPC32::CRRCRegisterClass }, { 0 }, };

For operand information, which does not require dynamic (startup-time)
initialization.

cef54bfd28 Refactor to use Target.getRegisterClasses consistently, which provides 
anonymous regclass definition renaming.

Change the generated code to emit register classes as properly namespace
qualified entities like everything else.

expose the actual class definition as an object, though this isn't quite
usable yet.

077a4e87c4 Emit real operand info for instructions. This currently works but is bad 
in one way: the generated tables require dynamic initialization for the
register classes.  This will be fixed in a future patch.

1685432a06 The code emitter generator only supports targets with 32-bit instruction 
words.  There is no way for one of these targets to have a > 32-bit immediate!

7ab998463c now that all of the targets are clean w.r.t. the number of operands for each 
instruction defined, actually emit this to the InstrInfoDescriptor, which
allows an assert in the machineinstrbuilder to do some checking for us,
and is required by the dag->dag emitter

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.
