Fix a bug in codegenprep where it was losing track of values OptimizeMemoryInst
by switching to a ValueMap. Patch by Andrea DiBiagio!

This patch fixes two tests marked as XFAIL among the ARM assembler tests.
The reference encoding is correct, but written in the wrong byte order (these are Thumb tests, while the reference is in ARM byte order).

PPCInstrInfo::optimizeCompareInstr should not optimize FP compares

The floating-point record forms on PPC don't set the condition register bits
based on a comparison with zero (like the integer record forms do), but rather
based on the exception status bits.

[PowerPC] Fix regression in generating @ha/@l relocs

The patch I committed as revision 167864 introduced a regression that
causes LLVM to no longer generate appropriate relocs for @ha/@l symbol
references (but fail an assertion instead).

This is fixed here by re-enabling support for the VK_PPC_GAS_HA16/
VK_PPC_GAS_LO16 variant kinds (and their Darwin variants) in
PPCELFObjectWriter.cpp.

Tested by running projects/test-suite in -m32 mode with the integrated
assembler forced on.  A standalone test case will be committed shortly
as well.

[PowerPC] Add some missing PPC64 relocs

All R_PPC_... relocs should also be present (using the same number)
under the corresponding R_PPC64_... name.   The latter were missing
for a couple of cases, which this patch adds.

This is not a big problem when emitting the reloc, because we can
just use the R_PPC_... define instead.  But it is a problem when
*dumping* relocations e.g. using llvm-readobj, because this will
expect only R_PPC64_... values when inspecting a ppc64 ELF file.

[PowerPC] Add ELF relocation tests

This patch extends test/MC/PowerPC/ppc64-fixups.s to not only check for
the correct fixup type in the --show-encoding output, but also runs the
generated object file through llvm-readobj -r and verifies that the
correct ELF relocation records were generated.

Pull up AssemblyWriter interface into header to allow subclassing
- made all functions virtual so that subclasses can specialize them
- add printInstructionLine so that subclasses can choose whether or not to
  print the newline character (without having to implement printBasicBlock()
- added a second constructor to AssemblyWriter that does not require a
  SlotTracker, as required in order to keep the SlotTracker helper class outside
  AsmWriter.h and buried in the implementation.

- requires existing debug information to be present
- fixes up file name and line number information in metadata
- emits a "<orig_filename>-debug.ll" succinct IR file (without !dbg metadata
  or debug intrinsics) that can be read by a debugger
- initialize pass in opt tool to enable the "-debug-ir" flag
- lit tests to follow
