Log:
    PR sanitizer/55439
    * Makefile.in (tsan.o): Depend on tree-ssa-propagate.h.
    * sanitizer.def: Add __tsan_atomic* builtins.
    * asan.c (initialize_sanitizer_builtins): Adjust to also
    initialize __tsan_atomic* builtins.
    * tsan.c: Include tree-ssa-propagate.h.
    (enum tsan_atomic_action): New enum.
    (tsan_atomic_table): New table.
    (instrument_builtin_call): New function.
    (instrument_gimple): Take pointer to gimple_stmt_iterator

    (instrument_memory_accesses): Adjust instrument_gimple caller.
    * builtin-types.def (BT_FN_BOOL_VPTR_PTR_I1_INT_INT,
