[cfe-dev] clang_getCursorExtent of macro instantiation

[Mert Akinc]

That doesn't exist in the version I'm using (2.9), but I'm using
clang_getInstantiationLocation which, from the documentation and observed
behavior, appears to be identical. I'm guessing it was just renamed to
clang_getExpansionLocation for clarity.
