PR sanitizer/56454
* asan.c (gate_asan): Lookup no_sanitize_address instead of
no_address_safety_analysis attribute.
* doc/extend.texi (no_address_safety_attribute): Rename to
no_sanitize_address attribute, mention no_address_safety_analysis
attribute as deprecated alias.
* c-common.c (handle_no_sanitize_address_attribute): New function.
(c_common_attribute_table): Add no_sanitize_address attribute.
(handle_no_address_safety_analysis_attribute): Add
no_sanitize_address attribute, not no_address_safety_analysis
attribute.
* g++.dg/asan/default-options-1.C (__asan_default_options): Use
no_sanitize_address attribute rather than no_address_safety_analysis.
* g++.dg/asan/sanitizer_test_utils.h
(ATTRIBUTE_NO_ADDRESS_SAFETY_ANALYSIS): Likewise.
* c-c++-common/asan/attrib-1.c: Test no_sanitize_address attribute
in addition to no_address_safety_analysis.
