[patch, fortran, RFC] First steps towards inlining matmul

[Thomas Koenig]

OK, here is a new version.

There is now an option for setting a maximum on the array size,
which takes its default from the BLAS limit (if specified).

Currently, only setting the maximum size to zero as a way of
disabling the unrolling is supported.  I have done this in a
few test cases.

The bugs reported by Dominique have now been fixed.

Still to do:  Bounds checking (a rather big one), honoring the
maximum size, test cases, ChangeLog, some more comments to the code.

Anything else?

Regards

	Thomas
