c74586940a the apple "ld_classic" linker doesn't support .literal16 in 32-bit 
mode, and "ld64" (the default linker) falls back to it in -static
mode.

b740190d2e - More refactoring. This gets rid of all of the getOpcode calls. 
- This change also makes it possible to switch between ARM / Thumb on a
  per-function basis.
- Fixed thumb2 routine which expand reg + arbitrary immediate. It was using
  using ARM so_imm logic.
- Use movw and movt to do reg + imm when profitable.
- Other code clean ups and minor optimizations.

55461787cc Rip all of the global variable lowering logic out of TargetAsmInfo. Since 
it is highly specific to the object file that will be generated in the end,
this introduces a new TargetLoweringObjectFile interface that is implemented
for each of ELF/MachO/COFF/Alpha/PIC16 and XCore.

Though still is still a brutal and ugly refactoring, this is a major step
towards goodness.

This patch also:
1. fixes a bunch of dangling pointer problems in the PIC16 backend.
2. disables the TargetLowering copy ctor which PIC16 was accidentally using.
3. gets us closer to xcore having its own crazy target section flags and
   pic16 not having to shadow sections with its own objects.
4. fixes wierdness where ELF targets would set CStringSection but not
   CStringSection_.  Factor the code better.
5. fixes some bugs in string lowering on ELF targets.

40bd748448 Make raw_null_ostream flush its buffer in its destructor, so that 
it conforms to the assertion added in r77245. This fixes a failure
