I guess this is OK for mainline. It reduces the amount of memory we
allocate, therefore improves performance and is suitable for stage3.
However, it'd be nice to have a plan for eliminating NON_LVALUE_EXPR
completely (perhaps based on Joseph's parser rewrite). In the meantime,
I think this is the best we can do for gcc 4.0.
