d106d72681 Non-fast-isel followup to 129634; correctly handle branches controlled 
by non-CMP expressions.  The executable test case (129821) would test
this as well, if we had an "-O0 -disable-arm-fast-isel" LLVM-GCC
tester.  Alas, the ARM assembly would be very difficult to check with
FileCheck.

The thumb2-cbnz.ll test is affected; it generates larger code (tst.w
vs. cmp #0), but I believe the new version is correct.

dc7e74edfa MCJIT section loading should just skip non-text sections rather than 
erroring out completely. Some modules produce sections that aren't referenced,
so it's friendlier to clients like LLDB to just skip them, at least for now.

d323e73950 CMake builds gold by default since revision 127466. This is 
inconsistent with autoconf, which by default set BINUTILS_INCDIR to
empty and exclude gold from target list.

5ff60c7364 Re-commit 131172 with fix. MachineInstr identity checks should check dead 
markers. In some cases a register def is dead on one path, but not on
another.

This is passing Clang self-hosting.

f6c2c6a38e Address the last bit of relocation flag related divergence betweeen 
LLVM and binutils.

With this patch, there are no functional differences between the .o
produced directly from LLVM versus the .s to .o via GNU as, for relocation tags
at least, for both PIC and non-PIC modes.

Because some non-PIC reloc tags are used (legally) on PIC, so IsPCRel flag is
necessary but not sufficient to determine whether the overall codegen mode is
PIC or not. Why is this necessary? There is an incompatibility of how relocs
are emitted in the .rodata section.  Binutils PIC likes to emit certain relocs
as section relative offsets.  Non-PIC does not do this.

So I added a hidden switch on the ELFObjectwriter "-arm-elf-force-pic" which
forces the objectwriter to pretend that all relocs are for PIC mode.


Todo: Activate ForceARMElfPIC to true if -relocation-model=pic is selected
on llc.

Todo: There are probably more issues for PIC mode on ARM/MC/ELF...

Todo: Existing tests in MC/ARM/elf-reloc*.ll need to be converted over to .s 
tests as well as expanded to cover the gamut.
