The TypeLoc hierarchy used the llvm::cast machinery to perform undefined
behavior by casting pointers/references to TypeLoc objects to derived types
and then using the derived copy constructors (or even returning pointers to
derived types that actually point to the original TypeLoc object).
Some context is in this thread:

Though it's spread over a few months which can be hard to read in the mail
archive.

for a CXFile containing device/inode/modification time.
Intended to be useful as a key associated with a unique file across
an indexing session.

Also, it was the only reason that `argc` and `argv` were being passed
into createDiagnostics, so remove those parameters and clean up callers.

Manually fix the order of UnwrappedLineParser.cpp as that one didn't
have its associated header as the first header.
This also uncovered a subtle inclusion order dependency as CLog.h didn't
include LLVM.h to pick up using declarations it relied upon.

-provide a "raw_ostream'ish" class to make it convenient to output logging info.
-use macros to automate a bit the logging functionality inside libclang functions
-when logging, print a stack trace if "LIBCLANG_LOGGING=2" environment is set.
-add logging to more functions.

before doing the comparison.
This is because we can't set "FirstInDeclGroup" consistently; for example, when visiting a DeclStmt we will set
it but we don't set it on the result of clang_getCursorDefinition for a reference of the same declaration.

DenseMap and the lookups associated with it.
Instead of lexing for preprocessor tokens, associating the annotation with the location in a map,
and later lookup in the map in order to adjust the cursor annotation, just annotate the cursor
while lexing for preprocessor tokens.

Previously type/storage qualifiers would not be annotated as the declaration they belonged to.
Just use the resulting source range of getRawCursorExtent() which is more correct
than what AnnotateTokensWorker::Visit() was adjusting it to.

this was ever a macro name and return a specific CXCursor_MacroExpansion cursor in such a case,
instead of the generic CXCursor_MacroDefinition.
Checking for macro name makes sure the identifier is not part of the identifier list in a
function macro.
While, in general, resolving identifiers in macro definitions to other macros may not be completely accurate,
it greatly improves functionality such as give-me-the-definition-of-this, which was not working at all
inside macro definitions.

use clang's formatter. Currently, formatter is used
to format declaration tags for xml comments. Since formatter
is in flux and its change will break several of the clang comment
tests, only a single tests is formatted using this facility.
Doug has reviewed and approved it for check-in.

the various stakeholders bump up the reference count. In particular,
the diagnostics engine now keeps the DiagnosticOptions object alive.
