asan: Fix up build_check_stmt gsi handling [PR117209]
gsi_safe_insert_before properly updates gsi_bb in gimple_stmt_iterator
in case it splits objects, but unfortunately build_check_stmt was in
some places (but not others) using a copy of the iterator rather than
the iterator passed from callers and so didn't propagate that to callers.
I guess it didn't matter much before when it was just using
gsi_insert_before as that really didn't change the iterator.
The !before_p case is apparently dead code, nothing is calling it with
before_p=false since around 4.9.

* asan.cc (maybe_cast_to_ptrmode): Formatting fix.
(build_check_stmt): Don't copy *iter into gsi, perform all
the updates on iter directly.
