    fortran: Remove reference count update [PR108957]

    Remove one reference count incrementation following the assignment of a
    symbol pointer to a local variable.  Most symbol pointers are "weak"
pointer
    and don't need any reference count update when they are assigned, and i=
t is
    especially the case of local variables.

    This fixes a memory leak with the testcase from the PR (not included).

            PR fortran/108957

    gcc/fortran/ChangeLog:

            * gfortran.h (gfc_symbol): Add comment documenting reference
counting.
            * parse.cc (parse_interface): Remove reference count
incrementation.=
