Fixes to enable TrackLiveTemps optimization on x86.

- Created new kRegRegStore instruction class for Movdrx, where the
  source is first, and the destination is second.

- Reverted neg_float and neg_double implementation to prevent confusion
  of register types when optimizations are performed.

- Swapped order of loads for wide values to prevent base pointer from
  being clobbered when the base pointer equals the low destination reg.

- Implemented opRegCopyWide for general purpose reg source to floating
  point reg destination and vice versa.

- Added more opcode coverage to x86 disassembler.
