This patch adds vmla selection.
MQPR :) Can you also try to format this line to be a little shorter.
Can you move this to test/CodeGen/Thumb2/mve-vmla.ll
Do these still select if the operands are reversed? It may be worth adding a few tests to show that.
We shouldn't be restricted to just using tGPR, rGPR looks like the best fit.
I'm wondering how we'd use the signed versions... but this LGTM.
