Per advice that Doug Gregor gave me several months ago, clean up the
implementation of '#pragma unused' by not constructing intermediate
DeclRefExprs, but instead do the name lookup directly. The
implementation is greatly simplified.
Along the way, degrade '#pragma unused(undeclaredvariable)' to a
warning instead of being a hard error. This implements:
<rdar://problem/6761874> [sema] allow #pragma unused to reference undefined variable (with warning)
