re PR sanitizer/77396 (address sanitizer crashes if all static global variables are optimized)
PR sanitizer/77396
* sanopt.c: Include gimple-ssa.h, tree-phinodes.h and ssa-iterators.h.
(sanopt_optimize_walker): Optimize away
__asan_before_dynamic_init (...) followed by
__asan_after_dynamic_init () without intervening memory loads/stores.
* ipa-pure-const.c (special_builtin_state): Handle
BUILT_IN_ASAN_BEFORE_DYNAMIC_INIT and
BUILT_IN_ASAN_AFTER_DYNAMIC_INIT.
* decl2.c (do_static_initialization_or_destruction): Only
call asan_dynamic_init_call if INITP is true.
* g++.dg/asan/pr77396.C: New test.
