RISCV: Avoid GlobalISel build break in a future patch 

The GlobalISelEmitter is stricter about matching timm instruction
outputs to timm inputs (although in an accidental sort of way that
doesn't hit a proper import failure error). Also, apparently no
intrinsic patterns were importing since the ID enum declaration was
missing.
