    c++: reinterpret_cast from prvalue to rvalue ref [PR98440]

    In r260622 I allowed this under the general principle that [basic.lval]
    "Whenever a prvalue appears as an operand of an operator that expects a
    glvalue for that operand, the temporary materialization conversion (7.3.4)
    is applied to convert the expression to an xvalue."  But
    [expr.reinterpret.cast] specifically excludes creating a temporary in this
    case.

    gcc/cp/ChangeLog:

            PR c++/98440
            * typeck.c (build_reinterpret_cast_1): Don't perform
            temporary materialization.

    gcc/testsuite/ChangeLog:

            * g++.dg/cpp0x/rv-cast6.C: Expect reinterpret_cast error.
            * g++.dg/cpp0x/reinterpret_cast2.C: Adjust message.
            * g++.old-deja/g++.jason/rvalue3.C: Likewise.
