* cfgexpand.c (expand_one_var): Add check if stack is going to
be used in naked function.
* expr.c (expand_expr_addr_expr_1): Remove excess checking
whether expression should not reside in MEM.
* function.c (use_register_for_decl): Do not use registers for
non-register things (volatile, float, BLKMode) in naked functions.
