  - Revert^4 "Partial Load Store Elimination"
    
    This reverts commit 791df7a161ecfa28eb69862a4bc285282463b960.
    This unreverts commit fc1ce4e8be0d977e3d41699f5ec746d68f63c024.
    This unreverts commit b8686ce4c93eba7192ed7ef89e7ffd9f3aa6cd07.
    
    We incorrectly failed to include PredicatedInstanceFieldGet in a few
    conditions, including a DCHECK. This caused tests to fail under the
    read-barrier-table-lookup configuration.
    
    Reason for revert: Fixed 2 incorrect checks
    
    Bug: 67037140
    Test: ./art/test/testrunner/run_build_test_target.py -j70 art-gtest-read-barrier-table-lookup
