[InstCombine] Disable branch predicate canonicalization by default

Authored by yrouban on Jul 24 2020, 12:26 AM.



Disabling the branch predicate canonicalization in InstCombine might affect many users. This transform is expected to be done by SimplifyCFG (D84492, D84491).
This one line patch allows a simple revert and further investigation for any found issues.
In future this transformation with its flag should be removed from InstCombine.
