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.

Eric Christopher cee313d288 Revert "Temporarily Revert "Add basic loop fusion pass."" 
The reversion apparently deleted the test/Transforms directory.

Will be re-reverting again.

Eric Christopher a863435128 Temporarily Revert "Add basic loop fusion pass." 
As it's causing some bot failures (and per request from kbarton).

This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda.

Geoff Berry f7d5daa0c0 [EarlyCSE] Handle calls with no MemorySSA info. 
Summary:
When checking for memory dependencies between calls using MemorySSA,
handle cases where the calls have no MemoryAccess associated with them
because the AA analysis being used has determined that the call does not
read/write memory.

Fixes PR33756
