bc3bc62709 Check in the first big step of rewriting DAGISelEmitter to 
produce a table based matcher instead of gobs of C++ Code.

Though it's not done yet, the shrinkage seems promising,
the table for the X86 ISel is 75K and still has a lot of 
optimization to come (compare to the ~1.5M of .o generated
the old way, much of which will go away).

The code is currently disabled by default (the #if 0 in
DAGISelEmitter.cpp).  When enabled it generates a dead
SelectCode2 function in the DAGISel Header which will
eventually replace SelectCode.

There is still a lot of stuff left to do, which are
documented with a trail of FIXMEs.

dynamic stack alignment would know whether it is required and whether frame
pointer register cannot be made available register allocation.

2fd80c3d94 Add a new pass on machine instructions to optimize away PHI cycles that 
reduce down to a single value.  InstCombine already does this transformation
but DAG legalization may introduce new opportunities.  This has turned out to
be important for ARM where 64-bit values are split up during type legalization:
InstCombine is not able to remove the PHI cycles on the 64-bit values but
the separate 32-bit values can be optimized.  I measured the compile time 
impact of this (running llc on 176.gcc) and it was not significant.

c17e781f35 The previous fix of widening divides that trap was too fragile as it depends on custom 
lowering and requires that certain types exist in ValueTypes.h.  Modified widening to
check if an op can trap and if so, the widening algorithm will apply only the op on
the defined elements.  It is safer to do this in widening because the optimizer can't
guarantee removing unused ops in some cases.

83ebc265b3 Reintroduce the InlineHint function attribute. 
This time it's for real! I am going to hook this up in the frontends as well.

The inliner has some experimental heuristics for dealing with the inline hint.
When given a -respect-inlinehint option, functions marked with the inline
keyword are given a threshold just above the default for -O3.

We need some experiments to determine if that is the right thing to do.

670458b3be Teach SimplifyCFG about magic pointer constants. 
Weird code sometimes uses pointer constants other than null. This patch
teaches SimplifyCFG to build switch instructions in those cases.

Code like this:

void f(const char *x) {
  if (!x)
    puts("null");
  else if ((uintptr_t)x == 1)
    puts("one");
  else if (x == (char*)2 || x == (char*)3)
    puts("two");
  else if ((intptr_t)x == 4)
    puts("four");
  else
    puts(x);
}

Now becomes a switch:

define void @f(i8* %x) nounwind ssp {
entry:
  %magicptr23 = ptrtoint i8* %x to i64            ; <i64> [#uses=1]
  switch i64 %magicptr23, label %if.else16 [
    i64 0, label %if.then
    i64 1, label %if.then2
    i64 2, label %if.then9
    i64 3, label %if.then9
    i64 4, label %if.then14
  ]

Note that LLVM's own DenseMap uses magic pointers.

92abe5abcc r94686 changed all ModuleProvider parameters to Modules, which made the 
1-argument ExecutionEngine::create(Module*) ambiguous with the signature that
used to be ExecutionEngine::create(ModuleProvider*, defaulted_params).  Fixed
by removing the 1-argument create().  Fixes PR6221.

837d242070 make MachineModuleInfoMachO hold non-const MCSymbol*'s instead 
of const ones.  non-const ones aren't very useful, because you can't
even, say, emit them.

e8811c3222 change addPassesToEmitFile to return true on failure instead of its input, 
add -filetype=null for performance testing and remove -filetype=dynlib,
which isn't planned to be implemented.

78f57ac8dc Hook up -filetype=obj through the MachO streamer. Here's a demo: 
$ cat t.ll 
@g = global i32 42
$ llc t.ll -o t.o -filetype=obj
$ nm t.o
00000000 D _g

There is still a ton of work left.  Instructions are not being encoded
yet apparently.

643f2f9bc4 refactor code so that LLVMTargetMachine creates the asmstreamer and 
mccontext instead of having AsmPrinter do it.  This allows other 
types of MCStreamer's to be passed in.

7dd4ad3ced Remove a bunch of stuff around the edges of the ELF writer. 
Now the only use of the ELF writer is the JIT, which won't be
easy to fix in the short term. :( :(

eliminate random "code emitter" stuff in Alpha, except for
the JIT path.  Next up, remove the template cruft.
