Draft patch, untested, currently bootstrapping

This patch adds a gfc_abstract_symbol class to abstract away the differences
between gfc_symbol and gfc_intrinsic_symbol.
Then the procedure symbol can be abstracted to a gfc_abstract_symbol, even if
it is intrinsic.
The change in symbol.c is necessary, otherwise the vptr is not set. I hope it
works that way.

Nope, it doesn't.  :-(

Patch for the ISFHTC optional SIZE argument

This patch addresses a bug when an optional dummy argument is passed as SIZE.

There is a separate, general issue with passing optional arguments to
elemental procedures, see PR113377.
