[patch/testsuite] cvexpr.c: data pointers vs function pointers

[Michael Elizabeth Chastain]

This match fixes cvexpr.c so that it respects the difference
between function pointers and data pointers.  I need this
for hp-ux 11 ansi c.

The problem:

  void use (void *) { ; }
  int (*fp)(int);
  use (fp);

The solution:

  void use (void *) { ; }
  int (*fp)(int);
  use (&fp);

This is simpler than writing a bunch of "void use_fpii_(int(*)(int))"
functions.

Tested on:

  native i686-pc-linux-gnu, gcc 2.95.3 3.3.2 HEAD, dwarf-2 stabs+
  native hppa2.0w-hp-hpux11.11, hp ansi c

I am committing this as obvious.
