8fbc00b5ba Fixed a bug in the enhanced disassembler that caused
it to ignore valid uses of FS and GS as additional
base registers in address computations.  Added a test
case for this.

disassembler. Fixes <rdar://problem/8958982>

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

7597212abc Model :upper16: and :lower16: as ARM specific MCTargetExpr. This is a step
in the right direction. It eliminated some hacks and will unblock codegen

e.g. (FOO - :lower16:BAR). It also doesn't work in Thumb2 mode at all.

62b83b62f3 Layout one section until no relaxations are done and then move to the next
section.

This helps because in practice sections form a dag with debug sections pointing
to text sections. Finishing up the text sections first makes the debug section
relaxation trivial.
