deduction. Unify all of the looping over template arguments for
deduction purposes into a single place, where argument pack expansion
occurs; this is also the hook for deducing from pack expansions, which
itself is not yet implemented.

For now, at least we can handle a basic "count" metafunction written
with variadics. See the new test for the formulation that works.

This change is necessary when the variable is a const reference and we need
the l-value of the construct expr.  After that, when binding the variable,
recover the lazy compound value when the variable is not a reference.

In Environment, use the value of a no-op cast expression when it has one.
Otherwise, blast-through it.

Previously designated anonymous fields were found via name lookup. This redesign uses the fact that an IndirectFieldDecl declaration will always follow an anonymous implicit field to remove the special case of name lookup.

inconsistent with the type that the builtin *should* have, forget
about the builtin altogether: we don't want subsequence analyses,
CodeGen, etc., to think that we have a proper builtin function.

C is protected from errors here because it allows one to use a
library builtin without having a declaration, and detects inconsistent
(re-)declarations of builtins during declaration merging. C++ was
unprotected, and therefore would crash.

classes, categories, protocols, and class extensions, where the
methods and properties of these entities would be inserted into the
DeclContext in an ordering that doesn't necessarily reflect source
order. The culprits were Sema::ActOnMethodDeclaration(), which did not
perform the insertion of the just-created method declaration into
the DeclContext for these Objective-C entities, and
Sema::ActOnAtEnd(), which inserted all method declarations at the
*end* of the DeclContext. 

With this fix in hand, clean up the code-completion actions for
property setters/getters that worked around this brokenness in the AST.

Fixes <rdar://problem/8062781>, where this problem manifested as poor

lists, so that all such transformations go through a single,
iterator-based transformation function. This is the only place where
we need to implement the logic for transforming pack expansions whose
pattern is a template argument.

Unfortunately, the new cases this refactoring brings into the fold
can't be meaningfully tested yet. We need template argument deduction
to work well enough for variadic function templates first.

shouldWalkTypesOfTypeLocs() that determines whether it should walk the
Types within TypeLocs. This walk is redundant, but perhaps required
for some clients. Disabling this redundant walk in the unexpanded
parameter pack finder produces better results, because we get
parameter packs with source location info *unless* such source
location information isn't available.

where OuterTypes and InnerTypes are template type parameter packs.

There is a horrible inefficiency in
TemplateArgumentLoc::getPackExpansionPattern(), where we need to
create copies of TypeLoc data because our interfaces traffic in
TypeSourceInfo pointers where they should traffic in TypeLocs
instead. I've isolated in efficiency in this one routine; once we
refactor our interfaces to traffic in TypeLocs, we can eliminate it.
