IndVarSimplify: check if loop invariant expansion can trap
IndVarSimplify is willing to move divide instructions outside of their
loop bodies if they are invariant of the loop. However, it may not be
safe to expand them if we do not know if they can trap.
Instead, check to see if it is not safe to expand the instruction and
skip the expansion.

prevent the CPU detect the loop (i.e. Loop-Stream-Detector seems to be working fine

The root cause of the problem is that the layout pass calls AnalyzeBranch()

instructions we support, LOAD REVERSED and STORE REVERSED may access

The same principle applies there: almost all memory instructions we
