[PATCH] PR53235: xfail scan-assembler-times in nested-4.C on darwin

[Jack Howarth]

   Current gcc trunk fails the scan-assembler-times on this test case
due to Apple's incomplete support for dwarf4. The attached patch xfail's
the scan-assembler-times on debug_types until Apple updates its cctools
to fully support dwarf4. Okay for gcc trunk?

ps I don't see a huge rush to dwarf-4 over on clang/llvm development with
the last mention at
