re PR middle-end/23125 (OpenBSD's zic.c causes g++ but not gcc to segfault)

* decl.c (make_rtl_for_nonlocal_decl): Use set_user_assembler_name
instead of change_decl_assembler_name.

* c-decl.c (finish_decl): Use set_user_assembler_name even for
register variables.
* varasm.c (make_decl_rtl): If a register variable does not
have a set user assmbler name, error out.
Decode the asmspec is now name+1 bypassing '*'.
