a87dea4f8c switch off of 'Section' onto MCSection. We're not properly using
MCSection subclasses yet, but this is a step in the right direction.

ff6ab17619 Until we have a "ALIGN" pseudo instruction, have asm printer emitted a .align
to ensure the instruction that follows a TBB (when the number of table entries
is odd) is 2-byte aligned.

d26b14c34c - Teach TBB / TBH offset limits are 510 and 131070 respectively since the offset
is scaled by two.
- Teach GetInstSizeInBytes about TBB and TBH.

7f93dc8345 Switch obvious clients to Twine instead of utostr (when they were already using
a Twine, e.g., for names).
 - I am a little ambivalent about this; we don't want the string conversion of
   utostr, but using overload '+' mixed with string and integer arguments is
   sketchy. On the other hand, this particular usage is something of an idiom.

6495f63945 - 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.

f0144127b9 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.
