location where we're spelling a token even within a
macro. clang_getInstantiationLocation() tells where we instantiated
the macro.
I'm still not thrilled with the CXSourceLocation/CXSourceRange APIs,
since they gloss over macro-instantiation information.
Take 2: this time, adjusted tests appropriately and used a "simple"
approach to the spelling location.

entities in the preprocessing record. Previously, we would only end up
getting the first token of a preprocessing record annotated
correctly. For example, given
#include "foo.h"
we would only get the '#' annotated as an inclusion directive; the
'include' and '"foo.h"' tokens would be given the general 'processing
directive' annotation.
Now, we get proper annotations for entities in the preprocessing
record.

inclusion directives, keeping track of every #include, #import,
etc. in the translation unit. We keep track of the source location and
kind of the inclusion, how the file name was spelled, and the
underlying file to which the inclusion resolved.

preprocessing record. Use that link with clang_getCursorReferenced()
and clang_getCursorDefinition() to match instantiations of a macro to
the definition of the macro.

the macro definitions and macro instantiations that are found
during preprocessing. Preprocessing records are *not* generated by
default; rather, we provide a PPCallbacks subclass that hooks into the
existing callback mechanism to record this activity.
The only client of preprocessing records is CIndex, which keeps track
of macro definitions and instantations so that they can be exposed via
cursors. At present, only token annotation uses these facilities, and
only for macro instantiations; both will change in the near
future. However, with this change, token annotation properly annotates
macro instantiations that do not produce any tokens and instantiations
of macros that are later undef'd, improving our consistency.
Preprocessing directives that are not macro definitions are still
handled by clang_annotateTokens() via re-lexing, so that we don't have
to track every preprocessing directive in the preprocessing record.
Performance impact of preprocessing records is still TBD, although it
is limited to CIndex and therefore out of the path of the main compiler.

directives while annotating tokens in CIndex. This functionality
should probably be factored out of this routine, but we're not there
yet.
