of a top-level declaration loads another top-level declaration of the
same name whose type depends on the first declaration having been
completed. This commit breaks the circular dependency by delaying
loads of top-level declarations triggered by loading a name until we
are no longer recursively loading types or declarations.

The implementations of these methods can Use Decl::getASTContext() to get the ASTContext.
This commit touches a lot of files since call sites for these methods are everywhere.
I used pre-tokenized "carbon.h" and "cocoa.h" headers to do some timings, and there was no real time difference between before the commit and after it.

C++. This logic is required to trigger implicit instantiation of
function templates and member functions of class templates, which will
be implemented separately.
This commit includes support for -Wunused-parameter, printing warnings
for named parameters that are not used within a function/Objective-C
method/block. Fixes <rdar://problem/6505209>.

within a template now have a link back to the enumeration from which
they were instantiated. This means that we can now find the
instantiation of an anonymous enumeration.

an integral constant expression, maintain a cache of the value and the
is-an-ICE flag within the VarDecl itself. This eliminates
exponential-time behavior of the Fibonacci template metaprogram.

template to the FunctionDecls from which they were instantiated. This
is a necessary first step to support instantiation of the definitions
of such functions, but by itself does essentially nothing.

'objc_ownership_cfretain' -> 'cf_ownership_retain'
'objc_ownership_cfrelease' -> 'cf_ownership_release'
Motivation: Core Foundation objects can be used in isolation from Objective-C,
and this forces users to reason about the separate semantics of CF objects. More
Sema support pending.

with PCH now but are not quite there yet.

'objc_ownership_cfrelease'. These are the 'release' equivalents of
'objc_ownership_retain' and 'objc_ownership_cfretain' respectively.

as 'objc_ownership_cfretain' except that the method acts like a CFRetain instead
of a [... retain] (important in GC modes). Checker support is wired up, but
currently only for Objective-C message expressions (not function calls).
