/* CAYMAN notes
Why CAYMAN got loops for lots of instructions is explained here.
-These 8xx t-slot only ops are implemented in all vector slots.
MUL_LIT, FLT_TO_UINT, INT_TO_FLT, UINT_TO_FLT
These 8xx t-slot only opcodes become vector ops, with all four
slots expecting the arguments on sources a and b. Result is
broadcast to all channels.
MULLO_INT, MULHI_INT, MULLO_UINT, MULHI_UINT, MUL_64
These 8xx t-slot only opcodes become vector ops in the z, y, and
x slots.
EXP_IEEE, LOG_IEEE/CLAMPED, RECIP_IEEE/CLAMPED/FF/INT/UINT/_64/CLAMPED_64
RECIPSQRT_IEEE/CLAMPED/FF/_64/CLAMPED_64
SQRT_IEEE/_64
SIN/COS
The w slot may have an independent co-issued operation, or if the
result is required to be in the w slot, the opcode above may be
issued in the w slot as well.
The compiler must issue the source argument to slots z, y, and x
