Subject: Revert^2 "Partial LSE analysis & store removal"

A ScopedArenaAllocator in a single test was accidentally loaded using
operator new which is not supported. This caused a memory leak.

This reverts commit fe270426c8a2a69a8f669339e83b86fbf40e25a1.
This unreverts commit bb6cda60e4418c0ab557ea4090e046bed8206763.

Bug: 67037140

Reason for revert: Fixed memory leak in
LoadStoreAnalysisTest.PartialEscape test case

Test: SANITIZE_HOST=address ASAN_OPTIONS=detect_leaks=0 m test-art-host-gtest-dependencies
      Run art_compiler_tests
