Address minor FIXME in RedeclLink to contain a PointerIntPair instead of derive from it.
Use actual factory functions rather than derived classes acting as named constructors/factories.

De-virtualize getPreviousDecl() and getMostRecentDecl() when we know
we have a redeclarable type, and only use the new virtual versions
(getPreviousDeclImpl() and getMostRecentDeclImpl()) when we don't have
that type information. This keeps us from penalizing users with strict
type information (and is the moral equivalent of a "final" method).
Plus, settle on the names getPreviousDecl() and getMostRecentDecl()
throughout.

Add a sanity check in the Redeclarable::redecl_iterator to avoid infinite loop
when we formed an invalid redeclaration chain due to a bug.
Thanks to Doug for the hint!

Re-implement caching for the linkage calculation of declarations.
My previous attempt at solving the compile-time problem with many
redeclarations of the same entity cached both linkage and visibility,
while this patch only tackles linkage. There are several reasons for
this difference:
- Linkage is a language concept, and is evaluated many times during
semantic analysis and codegen, while visibility is only a
code-generation concept that is evaluated only once per (unique)
declaration. Hence, we *must* optimize linkage calculations but
don't need to optimize visibility computation.
- Once we know the linkage of a declaration, subsequent
redeclarations can't change that linkage. Hence, cache
invalidation is far simpler than for visibility, where a later
redeclaration can completely change the visibility.
- We have 3 spare bits in Decl to store the linkage cache, so the
cache doesn't increase the size of declarations. With the
visibility+linkage cache, NamedDecl got larger.

Revert r120808, my previous implementation of caching for the linkage
and visibility of declarations, because it was extremely messy and it
increased the size of NamedDecl.
An improved implementation is forthcoming.

Implement caching for the linkage and visibility calculations of
declarations.
The motivation for this patch is that linkage/visibility computations
are linear in the number of redeclarations of an entity, and we've run
into a case where a single translation unit has > 6500 redeclarations
of the same (unused!) external variable. Since each redeclaration
involves a linkage check, the resulting quadratic behavior makes Clang
slow to a crawl. With this change, a simple test with 512
redeclarations of a variable syntax-checks ~20x faster than
before.
That said, I hate this change, and will probably end up reverting it
in a few hours. Reasons to hate it:
- It makes NamedDecl larger, since we don't have enough free bits in
Decl to squeeze in the extra information about caching.
- There are way too many places where we need to invalidate this
cache, because the visibility of a declaration can change due to
redeclarations (!). Despite self-hosting and passing the testsuite,
I have no confidence that I've found all of places where this cache
needs to be invalidated.

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.

Mangle based on the declaration we're given, not the canonical
declaration, since attributes that affect mangling may have been added
to subsequent declarations. However, to determine the linkage of the
declaration, we need to look at the canonical declaration. Fixes PR4412.
