WIP patch
The attached WIP patch fixes the issue for optional arguments of intrinsic type
except CHARACTER, but does not yet handle derived types. Regtests OK.
Enabling derived types does not work when they occur in an array constructor,
and the code would ICE on empty constructors of derived type.
I haven't understood yet how (and why) temporaries are generated for
procedure arguments even when it is known at compile-time that these have
size zero. I'd appreciate input from others.
