[PATCH] FileCheck: fix a bug with multiple --check-prefix options.

[Daniel Sanders]

  Well spotted. LGTM.

  One minor nit is that I think that the 'FOO: foo' line should probably be 'FOO: fo{{o}}' or similar. It makes no difference to this test though. My thinking is that that it's not obvious to new readers that FileCheck that it will happily match portions of its own directives. The presence of the curly braces should at least get these readers to question why they're there.
  Similarly for the 'CHECK:' line even though the CHECK line won't be present in the output of the first FileCheck command..
