and create separate decl nodes for forward declarations and the
definition," which appears to be causing significant Objective-C
breakage.

- Eagerly create ObjCInterfaceTypes for declarations.
- The two above changes lead to a 0.5% increase in memory use and no speed regression when parsing Cocoa.h. On the other hand, now chained PCH works when there's a forward declaration in one PCH and the interface definition in another.
- Add HandleInterestingDecl to ASTConsumer. PCHReader passes the "interesting" decls it finds to this function instead of HandleTopLevelDecl. The default implementation forwards to HandleTopLevelDecl, but ASTUnit's handler for example ignores them. This fixes a potential crash when lazy loading of PCH data would cause ASTUnit's "top level" declaration collection to change while being iterated.

region of interest (if provided). Implement clang_getCursor() in terms
of this traversal rather than using the Index library; the unified
cursor visitor is more complete, and will be The Way Forward.
Minor other tweaks needed to make this work:
- Extend Preprocessor::getLocForEndOfToken() to accept an offset
from the end, making it easy to move to the last character in the
token (rather than just past the end of the token).
- In Lexer::MeasureTokenLength(), the length of whitespace is zero.

statements, moving some of the more unnatural kinds of references
(VarRef, EnumConstantRef, etc.) over to the expressions. We can now
poke at arbitrary expressions and statements with, e.g.,
clang_getCursor() and get back useful information (e.g., source
ranges).

API. This is a catch-all for any declaration known to Clang but not
specifically part of the CIndex API. We'll use the same approach with
expressions, statements, references, etc., as needed.

CIndex functions that (1) map from a reference or declaration to the
corresponding definition, if available, and (2) determine whether a
given declaration cursor is also a definition. This eliminates a lot
of duplication in the cursor kinds, and maps more closely to the Clang
ASTs.
This is another API + ABI breaker with no deprecation. Yay, progress.

in CXCursor.cpp. With this sane representation, fix the class
reference that is part of Objective-C category declarations so that
the cursor's location matches up with the reference, not the class
being referred to.

piece of the declaration. The '@' and the 'end' are separate tokens,
and require two SourceLocations to accurately track.
This change was motivated because ObjCContainerDecl::getSourceRange()
would previously not return the entire range of the declaration (the
'end' would be left off).

- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).
