* c-common.c (handle_aligned_attribute, check_function_sentinel,
get_nonnull_operand, handle_sentinel_attribute,
check_function_arguments_recurse): Do not strip NOPS from
INTEGER_CSTs.
* c-decl.c (check_bitfield_type_and_width, build_enumerator):
Likewise.
* c-format.c (get_constant): Likewise.
* c-parser.c (c_parser_postfix_expression): Likewise.
* c-typeck.c (set_init_index): Likewise.
(convert_arguments): Don't check for NOP_EXPR containing integer
constant.
