    gccrs: Remove rust_unreachable from grs_langhook_pushdecl
    
    grs_langhook_pushdecl was being called after adding targetm.init_builtins() 
call to
    gccrs's setup, which caused ICE on aarch64 build targets.
    
    gcc/rust/ChangeLog:
    
            * rust-lang.cc (grs_langhook_pushdecl): Remove rust_unreachable().
