Allow multiple check prefixes in FileCheck.
This is useful if you want to run multiple variations of a single test, and the majority of check lines should be the same. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@194343 91177308-0d34-0410-b5e6-96231b3b80d8

.. 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.
