Summary: (PIC) pointers to function breakage; patch included

Initial Comment:
In the PIC backend, taking a poiner to a function
generated bad code
and calling a function-pointer didn't generate any code
at all.

The attached patch fixes a lot of this.  A regression
test is included.

The test doesn't actually run because of other bugs -
bogus extra data-memory declarations are produced for
the code-space function name 
symbols _call0 and _call1.
(This may be related to or same as 670275).

hand-editing ptrfunc.asm after compilation and before
assembly demonstrates that the function-pointer code is
working.
