Log:
    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.
