Constants defining how certain sequences should be outlined.
MachineOutlinerDefault
implies that the function is called with a call instruction, and a return must be emitted for the outlined function frame.
That is,
I1 OUTLINED_FUNCTION: I2 --> call OUTLINED_FUNCTION I1 I3 I2 I3 ret
MachineOutlinerTailCall
implies that the function is being tail called. A jump is emitted instead of a call, and the return is already present in the outlined sequence. That is,
I1 OUTLINED_FUNCTION: I2 --> jmp OUTLINED_FUNCTION I1 ret I2 ret

This determines which of three possible cases of a three source commute the source indexes correspond to taking into account any mask operands.
All prevents commuting a passthru operand. Returns -1 if the commute isn't possible. Case 0 - Possible to commute the first and second operands. Case 1 - Possible to commute the first and third operands. Case 2 - Possible to commute the second and third operands.

Return true for all instructions that only update the first 32 or 64-bits of the destination register and leave the rest unmodified.
This can be used to avoid folding loads if the instructions only update part of the destination register, and the non-updated part is not needed. e.g. cvtss2sd, sqrtss. Unfolding the load from these instructions breaks the partial register dependency and it can improve performance. e.g.:
movss (rdi), xmm0 cvtss2sd xmm0, xmm0
Instead of cvtss2sd (rdi), xmm0
FIXME: This should be turned into a TSFlags.
