Twines: Support numeric conversion directly (uitostr, etc).
 - Provides static constructors for doing number to string conversions without
   using temporaries.

 - There are several ways to do this, I think given the Twine constraints this
   is the simplest one.

 - One FIXME for fast number -> hex conversion.

 - Added another comment on one last major bit of perf work Twines need, which
   is to make raw_svector_ostream more efficient.

tADDrSPI doesn't have a predicate operand, but tADDhirr and tADDi3 have.

Remove memory corruption bug. string.c_str() was returning a temporary that was
dead before we used it.

Code clean up. No functionality changes.

- 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.

fix a casting problem on the llvm-x86_64-linux tester

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@77295 91177308-0d34-0410-b5e6-96231b3b80d8

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.

Teach instcombine to respect and preserve inbounds. Add inbounds
to a few tests where it is required for the expected transformation.

llvm-mc: Stop uniqueing string tokens, nothing actually uses this.

Replace dyn_castGetElementPtr with dyn_cast<GEPOperator>.

Grab the LLVMContext and parent Module of SI ahead of the
point where SI can get deleted. This fixes a use of free'd memory.
This fixes Externals/Povray.
