Create load store analysis pass

This CL separates load store analysis from LSE pass.

The load and store analysis in LSE pass records information
about heap memory accesses for arrays and fields.
Such information can also be used in the other optimizations like
instruction scheduling pass which can eliminate side-effect
dependencies between memory accesses to different locations.

Test: m test-art-host
Test: m test-art-target
Test: m test-art-host-gtest-load_store_analysis_test
Test: 530-checker-lse
