Summary: CC, aCC, and xlC compilers don't bid on assembly files (.s)

Initial Comment:
The CC (Sun), aCC (HP), and xlC (IBM) compiler adapters do not bid on assembly files.  Instead, they defer to the sourceExtensions defined in the GccCompatibleCCompiler definition (which doesn't include '.s').  

In addition, since these compiler adapters are bidding based on the GccCompatibleCCompiler definition, they are bidding on Fortran source files (.f, .for), even though the underlying compilers can't deal with them.

Attached is a proposed patch which moves the sourceExtension and headerExtension definitions into the derived adapters for each of the compilers in question, along with the start of a testsuite for each compiler (currently just verifying which files they bid on).

I have a couple of open questions associated with the attached patch:

1) The behavior of the Forte CC compiler changed with Forte 6.1 (Sunpro
5.2).  Prior to Forte 6.1, the .c++ extension was not supported (and the
compiler would reject it as an unknown file type).  With 6.1 and later, the
.c++ extension is supported.  So should the Forte adapter bid on .c++ files
(since they are currently supported) or not (since some compiler versions
won't be able to handle them).

2) The test suite only verifies that all of the files that are explicitly
supported are bid on, it doesn't test the behavior for files that it
shouldn't bid on.  Is there a recommended process for testing that
unrecognized extensions won't be bid on?

3) Based on some experiments, it looks like the extension comparison is
case-insensitive (for all platforms), however at least some of the
compilers I tested were case-sensitive in their handling of extensions (for
example, the Forte compiler will accept a .cpp extension, but will reject a
.CPP extension).  Should CC-tasks file matching be case-sensitive or
case-insensitive?  Or should it be determined by the compiler (Windows
compilers will probably be case-insensitive, while some Unix compilers will
be case-sensitive).
