Revert^2 "Partial Load Store Elimination"

This reverts commit 47ac53100303e7e864b7f6d65f17b23088ccf1d6.

There was a bug in LSE where we would incorrectly record the
shadow$_monitor_ field as not having a default initial value. This
caused partial LSE to be unable to compile the Object.identityHashCode
function, causing crashes. This issue was fixed in a parent CL. Also
updated all Offsets in LSE_test to be outside of the object header
regardless of configuration.

Test: ./test.py --host
Bug: 67037140

Reason for revert: Fixed issue with shadow$_monitor_ field and offsets
