[esan|cfrag] Disable load/store instrumentation for cfrag
Summary:
Adds ClInstrumentFastpath option to control fastpath instrumentation.
Avoids the load/store instrumentation for the cache fragmentation tool.
Renames cache_frag_basic.ll to working_set_slow.ll for slowpath
instrumentation test.
Adds the __esan_init check in struct_field_count_basic.ll.
