  Split report_conflicting_sanitizer_options(..., SANITIZE_ADDRESS | SANITIZE_HWADDRESS)
call into 2 calls as we don't have any option that would be
address+hwaddress (that conflicts as well).

	PR sanitizer/106132

gcc/ChangeLog:

	* opts.cc (finish_options): Use 2 calls to
         report_conflicting_sanitizer_options.

gcc/testsuite/ChangeLog:

	* c-c++-common/hwasan/arguments-3.c: Cover new ICE.
