mirror the description in the standard. Per DR1295, this means that binding a const / rvalue reference to a bit-field no longer "binds directly", and per P0135R1, this means that we materialize a temporary in reference binding after adjusting cv-qualifiers and before performing a derived-to-base cast. In C++11 onwards, this should have fixed the last case where we would materialize a temporary of the wrong type (with a subobject adjustment inside the MaterializeTemporaryExpr instead of outside), but we still have to deal with that possibility in C++98, unless we want to start using xvalues to represent materialized temporaries there too. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@289250 91177308-0d34-0410-b5e6-96231b3b80d8
