Temporarily Revert "Add basic loop fusion pass."
...
As it's causing some bot failures (and per request from kbarton).
This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda.

[PatternMatch] define m_FNeg using m_FSub
...
Using cstfp_pred_ty in the definition allows us to match vectors with undef elements.
This replicates the change for m_Not from D44076 / rL326823 and continues
towards making all pattern matchers allow undef elements in vectors.
