[PATCH] D126005: [GISel] Add identity and fneg combines for G_FMUL

[Michael Kitzan via Phabricator via llvm-commits]

mkitzan added a comment.

These are combines which seem generally beneficial (not architecture specific) from the closed source backend I work on. They are beneficial for our backend, so we have been upstreaming these combines to improve GISel.
