Summary:                    Feature enabling the CheckC*.cmake macros to use a
path to source code as well as supplied source code
Description: 
We often have our own .c file stored in our tree for TRY_RUN testing,
and it is convenient to be able to use CHECK_C_RUNS_SOURCE for testing
those .c files.  At the moment, CHECK_C_RUNS_SOURCE assumes the
incoming SOURCE  variable actually holds the source code - our
enhancement checks to see if SOURCE holds a valid file path first.  If
it DOES hold a valid file path, TRY_RUN then trys that .c file,
otherwise the existing CHECK_C_RUNS_SOURCE is preserved.  I don't know
of any sane pathname that would be valid C code or vice versa, so
there should be no danger of passing in a C source snippit and having
it mistaken for a file path.
