This is legalized the same way as G_FCEIL, etc. Just add it to the existing legalizer rule.

Also, add the missing switch statement in AArch64RegisterBankInfo.cpp to make sure G_FMA is always on an FPR.

Update arm64-vfloatintrinsics.ll, add a legalizer test for G_FMA, and add a regbankselect test for G_FMA.
