hwasan: support new dg-output format.

Browse source 
Supports change in libsanitizer where it newly reports:
READ of size 4 at 0xffffffffc3d4 tags: 02/01(00) (ptr/mem) in thread T0

So the 'tags' contains now 3 entries compared to 2 entries.

gcc/testsuite/ChangeLog:

	* c-c++-common/hwasan/alloca-outside-caught.c: Update dg-output.
	* c-c++-common/hwasan/heap-overflow.c: Likewise.
	* c-c++-common/hwasan/hwasan-thread-access-parent.c: Likewise.
	* c-c++-common/hwasan/large-aligned-1.c: Likewise.
	* c-c++-common/hwasan/stack-tagging-basic-1.c: Likewise.
