Eric Christopher a62270de2c Revert "Temporarily Revert "Add basic loop fusion pass.""
The reversion apparently deleted the test/Transforms directory.

; This bug has to do with the fact that constant propagation was implemented in
; terms of _logical_ not (! in C) instead of _bitwise_ not (~ in C). This was
; due to a spec change.
; Fix #2: The unary not instruction now no longer exists. Change to xor.
