Also fix a copy-and-paste error in a comment from my previous commit.
Finally, add an example of the benefit the typo correction callback adds
to TryNamespaceTypoCorrection--which happens to also tickle the above
caching problem, as the only way a non-namespace Decl would be added to
the possible corrections is if it was cached as the correction for a
previous instance of the same typo where the typo was corrected to a
non-namespace via a different code path.

improvement to the typo correction, as demonstrated in the added test).

Implement the missing pieces of Evaluate for _Complex types.  With that complete, remove some code from CGExprConstant which is no longer necessary.  While I'm here, a couple minor tweaks to _Complex-in-C++. (Specifically, make _Complex types literal types, and don't warn for _Complex int.)

is important because it's fairly common for headers (especially system
headers) to want to provide only those typedefs needed for that
particular header, based on some guard macro, e.g.,

#ifndef _SIZE_T
#define _SIZE_T
typedef long size_t;
#endif

which is repeated in a number of headers. The guard macro protects
against duplicate definitions. However, this means that only the first
occurrence of this pattern actually defines size_t, so the submodule
corresponding to this header has the only visible definition. If a
user then imports a different submodule from the same module, size_t
will be known but not visible, and therefore cannot be used.

By allowing redefinition of typedefs, each header that wants to define
size_t can do so independently, so it will be available in the
corresponding submodules.

to Redeclarable<NamespaceDecl>, so that we benefit from the improveed
redeclaration deserialization and merging logic provided by
Redeclarable<T>. Otherwise, no functionality change.

As a drive-by fix, collapse the "inline" bit into the low bit of the
original namespace/anonymous namespace, saving 8 bytes per
NamespaceDecl on x86_64.

More lambda work: semantic analysis of capturing 'this'.  It's a bit complicated, but we have to be careful about when exactly captures are marked given PotentiallyPotentiallyEvaluated contexts.  (Actually, it's not 100% correct yet, but it's close enough for the moment.)

This patch (and some of my other commits related to lambdas) is heavily based off of John Freeman's work-in-progress patches.

visible, eliminating the redundant (and less efficient)
getPreviousDeclaration() implementation.

This tweak uncovered an omission in the handling of
RedeclarableTemplateDecl, where we weren't making sure to search for
additional redeclarations of a template in other module files. Things
would be cleaner if RedeclarableTemplateDecl actually used Redeclarable.
