[PATCH] Add ALL to FileCheck

[Stephen Lin]

Just to clarify, the idea would be that with no check prefix on the
command line, the prefix will default to "CHECK" as it does currently;
with one or more prefix specified on the command line, there will be
no implied CHECK prefix but will instead be the one or more prefix(es)
specified.
