re PR sanitizer/55439 (ThreadSanitizer: handle atomic operations)

	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
	instead of gimple_stmt_iterator.  Call instrument_builtin_call
	on builtin call stmts.
	(instrument_memory_accesses): Adjust instrument_gimple caller.
	* builtin-types.def (BT_FN_BOOL_VPTR_PTR_I1_INT_INT,
	BT_FN_BOOL_VPTR_PTR_I2_INT_INT, BT_FN_BOOL_VPTR_PTR_I4_INT_INT,
	BT_FN_BOOL_VPTR_PTR_I8_INT_INT, BT_FN_BOOL_VPTR_PTR_I16_INT_INT): New.
