Don't inline GCC memory builtins if ASan is enabled.

2014-10-28 Max Ostapenko <m.ostapenko@partner.samsung.com>
* asan.h (asan_intercepted_p): New function.
* asan.c (asan_mem_ref_hasher::hash): Remove MEM_REF access size from
hash value construction. Call iterative_hash_expr instead of explicit
hash building.
(asan_mem_ref_hasher::equal): Change condition.
(has_mem_ref_been_instrumented): Likewise.
(update_mem_ref_hash_table): Likewise.
(maybe_update_mem_ref_hash_table): New function.
(instrument_strlen_call): Removed.
(get_mem_refs_of_builtin_call): Handle new parameter.
(instrument_builtin_call): Call maybe_update_mem_ref_hash_table instead
of instrument_mem_region_access if intercepted_p is true.
(instrument_mem_region_access): Instrument only base with len instead of
base and end with 1.
(build_check_stmt): Remove start_instrumented and end_instrumented
parameters.
(enum asan_check_flags): Remove ASAN_CHECK_START_INSTRUMENTED and
ASAN_CHECK_END_INSTRUMENTED. Change ASAN_CHECK_LAST.
(asan_expand_check_ifn): Remove start_instrumented and end_instrumented.
* builtins.c (expand_builtin): Include asan.h. Don't expand string/memory
builtin functions that have interceptors if ASan is enabled.
