Doug, please look at decltype-crash and instantiate-function-1.mm, I'm not sure
if they are actually testing the right thing / anything.

Entity can now refer to declarations that are not visible outside the translation unit.
It is a wrapper of a pointer union, it's either a Decl* for declarations that don't
"cross" translation units, or an EntityImpl* which is associated with the specific "visible" Decl.
Included is a test case for handling fields across translation units.

'index-test' is now able to provide additional info for a Decl, through multiple AST files:
-Find declarations
-Find definitions
-Find references

declaration in the AST.
The new ASTContext::getCommentForDecl function searches for a comment
that is attached to the given declaration, and returns that comment,
which may be composed of several comment blocks.
Comments are always available in an AST. However, to avoid harming
performance, we don't actually parse the comments. Rather, we keep the
source ranges of all of the comments within a large, sorted vector,
then lazily extract comments via a binary search in that vector only
when needed (which never occurs in a "normal" compile).
Comments are written to a precompiled header/AST file as a blob of
source ranges. That blob is only lazily loaded when one requests a
comment for a declaration (this never occurs in a "normal" compile).
The indexer testbed now supports comment extraction. When the
-point-at location points to a declaration with a Doxygen-style
comment, the indexer testbed prints the associated comment
block(s). See test/Index/comments.c for an example.
Some notes:
- We don't actually attempt to parse the comment blocks themselves,
beyond identifying them as Doxygen comment blocks to associate them
with a declaration.
- We won't find comment blocks that aren't adjacent to the
declaration, because we start our search based on the location of
the declaration.
- We don't go through the necessary hops to find, for example,
whether some redeclaration of a declaration has comments when our
current declaration does not. Similarly, we don't attempt to
associate a \param Foo marker in a function body comment with the
parameter named Foo (although that is certainly possible).
- Verification of my "no performance impact" claims is still "to be
done".

This tool will be the test bed for indexing related operations. It basically reads PCH files passed by the command line and performs various operations.
Currently it can accept a file:line:column which resolves to a declaration/statement and displays some information about them.
