[PATCH] D103038: [InstCombine] canonicalize cast before unary shuffle

[Simon Pilgrim via Phabricator via llvm-commits]

RKSimon added a comment.

LGTM - maybe add scalable vector test coverage (and a TODO to support them in the future?)

In DAG, we already pass shuffles through binops (both upward and downward), we should probably extend that to unaryops equivalents (although they will have to handle different src/dst types as well)
