Douglas Gregor 250ffb1fcb When we're deserializing a template parameter declaration, temporarily
use the translation unit as its declaration context, then deserialize
the actual lexical and semantic DeclContexts after the template
parameter is complete. This avoids problems when the DeclContext
itself (e.g., a class template) is dependent on the template parameter
(e.g., for the injected-class-name).

Douglas Gregor 87866ceda7 Implement proper (de-)serialization for explicit template argument
lists with zero template arguments. Fixes some seriously scary
crashers in C++ PCH.

Douglas Gregor d4c5ed038c Make the deserialization of C++ base class specifiers lazy, improving
the performance of C++ PCH and reducing stack depth in the reader.

Douglas Gregor f86c939bff When de-serializing a type that is supposed to be canonical, call
getCanonicalType() to make sure that the type we got back is actually
canonical. This is the case for most types, which always build a
canonical type when given canonical components. However, some types that
involve expressions in their canonicalization (e.g., array types with
dependent sizes) don't always build canonical types from canonical
components, because there is no such thing as a "canonical"
expression. Therefore, we do this extra mapping to ensure that the
canonical types we store are actually canonical.

Argyrios Kyrtzidis f24d569f9e Fix C++ PCH issue.
The canonical FunctionTemplateDecl contains the specializations but we cannot use getCanonicalDecl on Template because it may still be initializing.
Write and read it from PCH.

Argyrios Kyrtzidis 7f76d11dcc Store the pending implicit instantiations in the PCH and perform them at the end of the translation unit that
included the PCH, as God intended.

Argyrios Kyrtzidis 839bbacfb2 Apart from storing/retrieving the previous redeclaration from PCH, also store/retrieve the most recent
redeclaration. That way we are sure that the full redeclarations chain is loaded.

When using chained PCHs, first declarations point to the most recent redeclarations in the same PCH.
To address this use a REDECLS_UPDATE_LATEST record block to keep track of which first declarations need
to point to a most recent redeclaration in another PCH.

Argyrios Kyrtzidis 47470f2f3f Hide the specializations folding sets of ClassTemplateDecl as an implementation detail (InsertPos
leaks though) and add methods to its interface for adding/finding specializations.

Simplifies its users a bit and we no longer need to replace specializations in the folding set with
their redeclarations. We just return the most recent redeclarations.

As a bonus, it fixes http://llvm.org/PR7670.
