  Log Message:
  -----------
  [MC] Store implicit ops immediately after the TargetInsts table. NFC.

This shrinks MCInstrDesc (and hence the whole TargetInsts table) because
we can store a 16-bit offset value to access the implicit operands,
instead of a pointer. This also reduces the number of relocs that need
to be applied when LLVM is compiled as position-independent code.
