Currently the opcode is only valid if it is the same between all of the ports. This is possible to violate if the opcode is places into a memory location and then read in a non-uniform manner by the warp / wavefront. Moving this to a compile time constant makes it impossible to break this invariant. Reviewed By: JonChesterfield Differential Revision: https://reviews.llvm.org/D150115
