Extend the CIndex API with direct support for expressions and
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).
