target-arm: Collapse VSRI case into VSHL, VSLI 

Collapse some switch cases for VSRI into those for VSHL, VSLI,
since the bodies are the same. (This is not completely obvious
for the size < 3 case, but since for VSRI we know U=1 the
GEN_NEON_INTEGER_OP() expansion is equivalent to the open-coded
VSHL/VSLI case.)
