	PR asan/56330
	* asan.c (get_mem_refs_of_builtin_call): White space and style
	cleanup.

	instrumented.  Simplify the logic by putting all the statements
	instrument 'base + len' inside a sequence, and then insert that
	sequence right before the current insertion point.  Then, to
	instrument 'base + len', just get an iterator on that statement.
	And do not forget to update the pointer to iterator the function
	received as argument.

	Avoid instrumenting duplicated memory access in the same basic block
	* Makefile.in (asan.o): Add new dependency on hash-table.h
	* asan.c (struct asan_mem_ref, struct mem_ref_hasher): New types.

	(instrument_derefs, instrument_mem_region_access): Insert the
	instrumented memory reference into the hash table.
	(maybe_instrument_assignment): Renamed instrument_assignment into
	this, and change it to advance the iterator when instrumentation
	actually happened and return true in that case.  This makes it
	homogeneous with maybe_instrument_assignment, and thus give a
	chance to callers to be more 'regular'.
	(transform_statements): Clear the memory reference hash table
	whenever we enter a new BB, when we cross a function call, or when
	we are done transforming statements.  Use
	maybe_instrument_assignment instead of instrumentation.  No more
	need to special case maybe_instrument_assignment and advance the
	iterator after calling it; it's now handled just like
	maybe_instrument_call.  Update comment.
