Rework the way we track which declarations are "used" during
compilation, and (hopefully) introduce RAII objects for changing the
"potentially evaluated" state at all of the necessary places within
Sema and Parser. Other changes:
- Set the unevaluated/potentially-evaluated context appropriately
during template instantiation.
- We now recognize three different states while parsing or
instantiating expressions: unevaluated, potentially evaluated, and
potentially potentially evaluated (for C++'s typeid).
- When we're in a potentially potentially-evaluated context, queue
up MarkDeclarationReferenced calls in a stack. For C++ typeid
expressions that are potentially evaluated, we will play back
these MarkDeclarationReferenced calls when we exit the
corresponding potentially potentially-evaluated context.
- Non-type template arguments are now parsed as constant
expressions, so they are not potentially-evaluated.
