tree.h (force_fit_type_double): Remove unused final argument.
* tree.h (force_fit_type_double): Remove unused final argument.
* c-common.c (constant_expression_warning): Replace use of
TREE_CONSTANT_OVERFLOW with TREE_OVERFLOW.
(convert_and_check): Likewise.
(shorten_compare): Update call to force_fit_type_double.
(c_common_truthvalue_conversion) <INTEGER_CST>: Use integer_zerop.
* convert.c (convert_to_pointer): Update call to
force_fit_type_double.
* fold-const.c (force_fit_type_double): Remove overflowed_const
argument.
(int_const_binop, fold_convert_const_int_from_int,
fold_convert_const_int_from_real, fold_div_compare,
fold_sign_changed_comparison, fold_unary, fold_negate_const,
fold_abs_const, fold_not_const): Remove the final argument from
calls to force_fit_type_double.
