57caad7a33 Preliminary support for ARM frame save directives emission via MI flags.
This is just very first approximation how the stuff should be done
(e.g. ARM-only for now). More to follow.

89e0f386f3 Be nice to Xcore and the XMOS assembler and avoid quoting section names
that contain only letters, digits and the characters "_" and ".".

78c1e1781c PR9352: Always emit a relocation for weak symbols. Not emitting relocations
for calls to weak symbols with a definition has the appearance of working
with LLVM-generated code because weak symbol definitions are put in their
own sections.

33b7bebca4 Revert r125595, which is an X86-only undocumented assembly syntax extension
enabled for all targets. Non-X86 targets should not have this behavior
enabled by default.

Joerg, if you would like to resubmit with the behavior conditionalized to be
X86-ELF only, that's fine.

953a2a3dee Teach ARM/MC/ELF about gcc compatible reloc output to get past odd linkage
failures with relocations.

The code committed is a first cut at compatibility for emitted relocations in
ELF .o.

Why do this? because existing ARM tools like emitting relocs symbols as
explicit relocations, not as section-offset relocs.

Result is that with these changes,
1) relocs are now substantially identical what to gcc outputs.
2) larger apps (including many spec2k tests) compile, cross-link, and pass

Added reminder fixme to tests for future conversion to .s form.

685c350ae7 Teach ARM/MC/ELF to handle R_ARM_JUMP24 relocation type for conditional jumps.
(yes, this is different from R_ARM_CALL)

- Adds a new method getARMBranchTargetOpValue() which handles the
  necessary distinction between the conditional and unconditional br/bl
  needed for ARM/ELF

At least for ARM mode, the needed fixup for conditional versus unconditional
br/bl is identical, but the ARM docs and existing ARM tools expect this
reloc type...

Added a few FIXME's for future naming fixups in ARMInstrInfo.td
