Bryan Chan 3404add468 [EarlyCSE] Verify hash code in regression tests
As discussed in D86843, -earlycse-debug-hash should be used in more regression
tests to catch inconsistency between the hashing and the equivalence check.

Yevgeny Rouban 5e5af533ab [IR] Fix mayReadFromMemory() for writeonly calls
Current implementation of Instruction::mayReadFromMemory()
returns !doesNotAccessMemory() which is !ReadNone. This
does not take into account that the writeonly attribute
also indicates that the call does not read from memory.

The patch changes the predicate to !doesNotReadMemory()
that reflects the intended behavior.
