Avoid crash after StopMacroExpansion
c848109 
When a splice throws a StopMacroExpansion, it's replaced by an
EmptyTree, which has NoType.  Which means you can't cast it, as you
can't call .asInstanceOf on it.  So handle this before calling
ensureConforms.

Use ??? instead of EmptyTree for StopMacroExpansion.
