PR c/54103
* c-typeck.c (build_unary_op): Pass original argument of
TRUTH_NOT_EXPR to c_objc_common_truthvalue_conversion, then remove
any C_MAYBE_CONST_EXPR, if it has integer operands.
(build_binary_op): Pass original arguments of TRUTH_ANDIF_EXPR,
TRUTH_ORIF_EXPR, TRUTH_AND_EXPR, TRUTH_OR_EXPR and TRUTH_XOR_EXPR
to c_objc_common_truthvalue_conversion, then remove any
C_MAYBE_CONST_EXPR, if they have integer operands. Use
c_objc_common_truthvalue_conversion not
c_common_truthvalue_conversion.
(c_objc_common_truthvalue_conversion): Build NE_EXPR directly and
call note_integer_operands for arguments with integer operands
that are not integer constants.
