re PR sanitizer/65367 (indefinite loop occurs with sanitize enabled and certain optimization options)

	PR sanitizer/65367
	* ubsan.c (ubsan_expand_objsize_ifn): Update GSI instead of GSI_ORIG
	when only removing the statement.  Handle expanding UBSAN_OBJECT_SIZE
	separately.

	* c-c++-common/ubsan/pr65367.c: New test.
