13353 (maybe_instrument_assignment): Renamed instrument_assignment into
13354 this, and change it to advance the iterator when instrumentation
13355 actually happened and return true in that case. This makes it
13356 homogeneous with maybe_instrument_assignment, and thus give a
13357 chance to callers to be more 'regular'.
13358 (transform_statements): Clear the memory reference hash table
13359 whenever we enter a new BB, when we cross a function call, or when
13360 we are done transforming statements. Use
13361 maybe_instrument_assignment instead of instrumentation. No more
13362 need to special case maybe_instrument_assignment and advance the
13363 iterator after calling it; it's now handled just like
13364 maybe_instrument_call. Update comment.
