re PR sanitizer/79572 (reference binding to null pointer not reported with -fsanitize=undefined)
PR c++/79572
* c-ubsan.h (ubsan_maybe_instrument_reference): Change argument to
tree *.
* c-ubsan.c (ubsan_maybe_instrument_reference): Likewise. Handle
not just NOP_EXPR to REFERENCE_TYPE, but also INTEGER_CST with
REFERENCE_TYPE.
* cp-gimplify.c (cp_genericize_r): Sanitize INTEGER_CSTs with
REFERENCE_TYPE. Adjust ubsan_maybe_instrument_reference caller
for NOP_EXPR to REFERENCE_TYPE.
* g++.dg/ubsan/null-8.C: New test.
