Carry lookup configuration throughout lookup on the LookupResult. Give
...
LookupResult RAII powers to diagnose ambiguity in the results. Other diagnostics
(e.g. access control and deprecation) will be moved to automatically trigger
during lookup as part of this same mechanism.
This abstraction makes it much easier to encapsulate aliasing declarations
(e.g. using declarations) inside the lookup system: eventually, lookup will
just produce the aliases in the LookupResult, and the standard access methods
will naturally strip the aliases off.

Per advice that Doug Gregor gave me several months ago, clean up the
...
implementation of '#pragma unused' by not constructing intermediate
DeclRefExprs, but instead do the name lookup directly. The
implementation is greatly simplified.
Along the way, degrade '#pragma unused(undeclaredvariable)' to a
warning instead of being a hard error. This implements:
<rdar://problem/6761874> [sema] allow #pragma unused to reference undefined variable (with warning)

Remove the ASTContext parameter from the attribute-related methods of Decl.
...
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.
