[PATCH,FORTRAN 10/29] Do not copy name for check_function_name

[Bernhard Reutner-Fischer]

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

Copying the sym->name ruins pointer equality checks and first and
foremost is not needed nowadays.

gcc/fortran/ChangeLog:

2018-09-02  Bernhard Reutner-Fischer  <al...@gcc.gnu.org>

        * decl.c (gfc_match_volatile, gfc_match_asynchronous): Do not
        copy sym->name.
