ubsan.h (ubsan_create_data): Change second argument's type to const location_t *.

	* ubsan.h (ubsan_create_data): Change second argument's type
	to const location_t *.
	* ubsan.c (ubsan_source_location): If xloc.file is NULL, set it to
	_("<unknown>").
	(ubsan_create_data): Change second argument to const location_t *PLOC.
	Create Loc field whenever PLOC is non-NULL.
	(ubsan_instrument_unreachable, ubsan_expand_null_ifn,
	ubsan_build_overflow_builtin, instrument_bool_enum_load): Adjust
	callers.

	* c-ubsan.c (ubsan_instrument_division, ubsan_instrument_shift,
	ubsan_instrument_vla, ubsan_instrument_return): Adjust
	ubsan_create_data callers.
