optinfo-emit-json.cc: don't call get_fnname_from_decl (PR middle-end/89725)

optrecord_json_writer::optinfo_to_json can in theory be called from any
optimization pass, but currently uses get_fnname_from_decl, which
is RTL-specific.

In that PR, Jakub suggested using either DECL_ASSEMBLER_NAME or the
"printable name" (via current_function_name).

This patch makes it use DECL_ASSEMBLER_NAME.

gcc/ChangeLog:
        PR middle-end/89725
        * optinfo-emit-json.cc (optrecord_json_writer::optinfo_to_json):
        Use DECL_ASSEMBLER_NAME rather than get_fnname_from_decl.
