[Bernhard Reutner-Fischer via Fortran]

From: Bernhard Reutner-Fischer <al...@gcc.gnu.org>

gcc/fortran/ChangeLog:

        * resolve.c (resolve_fl_procedure): Initialize
        allocatable_or_pointer.

---
fortran/resolve.c: In function 'bool resolve_fl_procedure(gfc_symbol*, int)':
fortran/resolve.c:13391:7: warning: 'allocatable_or_pointer' may be used 
uninitialized in this function [-Wmaybe-uninitialized]
13390 |   if (sym->attr.elemental && sym->result
      |       ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
13391 |       && allocatable_or_pointer)
      |       ^~~~~~~~~~~~~~~~~~~~~~~~~
.../fortran/resolve.c:13197:8: note: 'allocatable_or_pointer' was declared here
13197 |   bool allocatable_or_pointer;
      |        ^~~~~~~~~~~~~~~~~~~~~~

Bootstrapped and regtested without regressions.
Ok for trunk?
