Fix a test that hasn't worked since 2007

Due to a missing -verify, 2007-10-01-BuildArrayRef.c was a no-op.

The message was changed 5 years ago so also update the test to reflect the new wording.

There's no such thing as %clang_cc1_only

These were being substituted into approximately the following:

  clang -cc1 -internal-isystem ../lib/clang/3.5/include_only
