- df_live is already present at -O2, so we only need to add it and
mark all blocks dirty for -O
- df_process_deferred_rescans should be enough to force a rescan of
blocks affected by moving invariants, but calling it in find_defs
means that we don't do any rescans for the final loop

This testcase manages to find a way to look up the partial instantiation of
B for the default argument of C before we've created the partial
instantiation of B as part of the normal instantiation of the members of A.
Which we can deal with, but we were getting confused because the partial
instantiation was stored with a RECORD_TYPE specialization rather than
TEMPLATE_DECL.
