Partial revert of "Reduce using ArtMethod's dex_cache_resolved_types_."

Change Ic45a5ff8c66b79429e440cbc08d67bf22a083682 made the resolution
from true to false, assuming we could only enter that specific code
with a resolved type. Unfortunately b/34440020 shows we still
need to resolve.

Also move arg to a Handle, now that we are resolving, which could
lead to thread suspension.
