Douglas Gregor b242683d99 Overhaul checking of non-type template arguments that should refer to
an object or function. Our previous checking was too lax, and ended up
allowing missing or extraneous address-of operators, among other
evils. The new checking provides better diagnostics and adheres more
closely to the standard.

Fixes PR6563 and PR6749.

Douglas Gregor f5af3584ca Improve diagnostics when an elaborated-type-specifer containing a
nested-name-specifier (e.g., "class T::foo") fails to find a tag
member in the scope nominated by the
nested-name-specifier. Previously, we gave a bland

  error: 'Nested' does not name a tag member in the specified scope

which didn't actually say where we were looking, which was rather
horrible when the nested-name-specifier was instantiated. Now, we give
something a bit better:

  error: no class named 'Nested' in 'NoDepBase<T>'

Douglas Gregor e677dafce1 Change the representation of dependent elaborated-type-specifiers
(such as "class T::foo") from an ElaboratedType of a TypenameType to a
DependentNameType, which more accurately models the underlying
concept.

Improve template instantiation for DependentNameType nodes that
represent nested-name-specifiers, by performing tag name lookup and
checking the resulting tag appropriately. Fixes PR5681.

There is still much testing and cleanup to do in this area.

Argyrios Kyrtzidis 998d51b98f When "delayed parsing" C++ default arguments, if there is an error, there may be tokens left in the token stream
that will interfere (they will be parsed as if they are after the class' '}') and a crash will occur because
the CachedTokens that holds them will be deleted while the lexer is still using them.

Make sure that the tokens of default args are removed from the token stream.
Fixes PR6647.

Douglas Gregor 504662f28f Add a test for C++ [stmt.select]p3, which specifies that redeclaring a
name in the outermost block of a if/else that declares the same name
is ill-formed. Turns out that Clang and MSVC were right about PR6739;
GCC is too lax.

John McCall 16df1e59f2 Propagate the "found declaration" (i.e. the using declaration instead of
the underlying/instantiated decl) through a lot of API, including "intermediate"
MemberExprs required for (e.g.) template instantiation.  This is necessary
because of the access semantics of member accesses to using declarations:
only the base class *containing the using decl* need be accessible from the
naming class.

This allows us to complete an access-controlled selfhost, if there are no
recent regressions.

template partial specialization or function template, or when

Douglas Gregor d5cb1ddb2c After performing template argument deduction for a function template,
check deduced non-type template arguments and template template
arguments against the template parameters for which they were deduced,
performing conversions as appropriate so that deduced template
arguments get the same treatment as explicitly-specified template
arguments. This is the bulk of PR6723.

Also keep track of whether deduction of a non-type template argument
came from an array bound (vs. anywhere else). With this information,
we enforce C++ [temp.deduct.type]p17, which requires exact type
matches when deduction deduces a non-type template argument from
something that is not an array bound.

Finally, when in a SFINAE context, translate the "zero sized
arrays are an extension" extension diagnostic into a hard error (for
better standard conformance), which was a minor part of PR6723.
