Max Kazantsev f7019c8d31 [GVN] Prevent ScalarPRE from hoisting across instructions that don't pass control flow to successors 
This is to address a problem similar to those in D37460 for Scalar PRE. We should not
PRE across an instruction that may not pass execution to its successor unless it is safe
to speculatively execute it.
