[patch, fortran] Handle missing optional MASK for intrinsics


Hello world,

here is my New Year's Eve Eve patch. It handles passing absent optional
argument to intrinsics.

The library side is pretty straightforward: If the argument is absent,
pass a NULL pointer to the library routines and let them do the
right thing.

With the inlined versions, I had some more trouble.  Putting in
IF (.NOT. PRESENT(MASK)) into the condition was straightforward
engough (and should be moved outside the loops by optimization).

What caused me some problems was that, in the scalarizer, the bounds
for the generated loops were taken from the MASK argument,
which, in the case of an absent MASK, were of course uninitialized.

For the one-dimensional cases, I got around that by switching the
way these arguments are handed off to the scalarizer (see patch).

For the case of a multi-dimensional cases, I tried some open-heart
surgery on the scalarizer data structures, but all I got in return
were ICEs. So, I decided to pass this on to the library routines,
with a FIXME in the code.

So, OK for trunk?

Regards

	Thomas
