94b590f8fa ARM: allow vanilla expressions for movw/movt.
Expressions for movw/movt don't always have an :upper16: or :lower16:
on them and that's ok. When they don't, it's just a plain [0-65536]
immediate result, effectively the same as a :lower16: variant kind.

7b25ecf6ad ARM BL/BLX instruction fixups should use relocations.
We on the linker to resolve calls to the appropriate BL/BLX instruction
to make interworking function correctly. It uses the symbol in the
relocation to do that, so we need to be careful about being too clever.

To enable this for ARM mode, split the BL/BLX fixup kind off from the
unconditional-branch fixups.

ffa3225e26 ARM assembly parsing for MOV (immediate).
Add range checking for the immediate operand and handle the "mov" mnemonic
choosing between encodings based on the value of the immediate. Add tests
for fixups, encoding choice and values, and diagnostic for out of range values.

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
