Make the deserialization of macro definitions lazy, so that we can
...
load identifiers without loading their corresponding macro
definitions. This is likely to improve PCH performance slightly, and
reduces deserialization stack depth considerably when using
preprocessor metaprogramming.

Extend the preprocessing record and libclang with support for

inclusion directives, keeping track of every #include, #import,

kind of the inclusion, how the file name was spelled, and the
underlying file to which the inclusion resolved.

builtin preprocessor macro. This appears to work with two caveats:
