PR c++/68508
* cp-tree.h (cp_ubsan_maybe_instrument_downcast): Add INTYPE argument.
* cp-ubsan.c (cp_ubsan_maybe_instrument_downcast): Likewise. Use
it instead of or in addition to TREE_TYPE (op). Use
is_properly_derived_from, return NULL_TREE if TREE_TYPE (intype) and
TREE_TYPE (type) are the same type minus qualifiers.
* typeck.c (build_static_cast_1): Adjust callers.
* g++.dg/ubsan/pr68508.C: New test.
