ce79a25980 rename createX86MCCodeEmitter to more accurately reflect what it creates.

12ce0de462 Added support for X86 instruction prefixes so llvm-mc can assemble them. The 
Lock prefix, Repeat string operation prefixes and the Segment override prefixes.
Also added versions of the move string and store string instructions without the
repeat prefixes to X86InstrInfo.td. And finally marked the rep versions of
move/store string records in X86InstrInfo.td as isCodeGenOnly = 1 so tblgen is
happy building the disassembler files.

d269a6e460 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.

c760be99db Finally eliminate printMCInst and send instructions through 
the streamer.  Demo:

$ cat t.ll 
define i32 @test() nounwind {
  ret i32 42
}
$ llc t.ll -o -
...
_test: 
	movl	$42, %eax
	ret
$ llc t.ll -o t.o -filetype=obj
$ otool -tv t.o 
t.o:
(__TEXT,__text) section
_test:
00000000	movl	$0x0000002a,%eax
00000005	ret

d1ff72b8a7 rejigger the world so that EmitInstruction prints the \n at 
the end of the instruction instead of expecting the caller to
do it.  This currently causes the asm-verbose instruction 
comments to be on the next line.

0d883e3f84 sink handling of target-independent machine instrs (other

90567c3560 ByVal frame object size should be that of the byval argument, not the size of the type which is just a pointer. This is not known to break stuff but is wrong nevertheless.

b2c9290a01 Perform sibcall in some cases when arguments are passes memory. Look for cases 
where callee's arguments are already in the caller's own caller's stack and
they line up perfectly. e.g.

extern int foo(int a, int b, int c);

int bar(int a, int b, int c) {
  return foo(a, b, c);
}
