  Log Message:
  -----------
  [AMDGPU] Have a subtarget feature to control use of real True16 instructions.

Real True16 instructions are as they are defined in the ISA. Fake True16
instructions are identical to real ones except that they take 32-bit
registers as operands and always use their low halves.
