It is incorrect to assume that src[0] of a SEND-from-GRF opcode is the GRF. For example, FS_OPCODE_UNIFORM_PULL_CONSTANT_LOAD uses src[1] for the GRF. To be safe, loop over all the source registers and mark any GRFs. We probably won't ever have more than one, but it's simpler to just check all three rather than attempting to bail early. Not observed to fix anything yet, but likely to. Parallels the bug fix in the previous commit, which actually does fix known failures.
