[PATCH] D148520: [VP] Add more functional SD opcodes to definitions

[Luke Lau via Phabricator via llvm-commits]

luke added a comment.

So from what I can tell, VPMatchContext can now make VP nodes from FP_EXTEND and FP_FMAD. However there's no observable change because with the former, `TLI.isFPExtFoldable` returns false on RISC-V, and with the latter it's explicitly disabled with a FIXME to re-enable it at some point. 
But I've removed the NFC anyway: I believe these nodes are equivalent so these folds should be correct if they are ever enabled.
