c4b94e02af Rewrite FP constant handling in DEBUG_VALUE yet
again, so it more or less handles long double.

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.

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:

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.

14c38ec2af Remove the argument from EmitJumpTableInfo, because it doesn't need it.

AsmPrinter::EmitFunctionBody, which works by calling the virtual
EmitInstruction method.

589c6f620e Move getJTISymbol from MachineJumpTableInfo to MachineFunction,
which is more convenient, and change getPICJumpTableRelocBaseExpr
to take a MachineFunction to match.

Next, move the X86 code that create a PICBase symbol to
X86TargetLowering::getPICBaseSymbol from 
X86MCInstLower::GetPICBaseSymbol, which was an asmprinter specific 
library.  This eliminates a 'gross hack', and allows us to
implement X86ISelLowering::getPICJumpTableRelocBaseExpr which now
calls it.

This in turn allows us to eliminate the 
X86AsmPrinter::printPICJumpTableSetLabel method, which was the
only overload of printPICJumpTableSetLabel.

23cdb0bdcf DEBUG_VALUE is now variable sized, as it has a
target-dependent memory address representation in it.
Restore X86 printing of DEBUG_VALUE; lowering is
done in X86RegisterInfo using the normal algorithm.

3752d2fe34 Revert 93499. After discussion with Chris we agreed
FrameIndexes should be lowered, but the same way as
everything else (target dependent) rather than in a
special hacked way.  The lowering needs to be done
for eventual purposes of Dwarf generation.

71c25b7d7b Re-instate MOV64r0 and MOV16r0, with adjustments to work with the
new AsmPrinter. This is perhaps less elegant than describing them
in terms of MOV32r0 and subreg operations, but it allows the
current register to rematerialize them.
