Allow multiple check prefixes in FileCheck.

Browse Source 
This is useful if you want to run multiple variations
of a single test, and the majority of check lines
should be the same.

.. option:: --check-prefix prefix
FileCheck searches the contents of ``match-filename`` for patterns to match.
By default, these patterns are prefixed with "``CHECK:``". If you'd like to
use a different prefix (e.g. because the same input file is checking multiple
different tool or options), the :option:`--check-prefix` argument allows you
to specify a specific prefix to match.

change for different run options, but most lines remain the same.
