[libclang] Make clang_getCursor able to handle locations that point inside macro arguments.
e.g. for:
\define INVOKE(METHOD, CLASS) [CLASS METHOD]
void test2() {
INVOKE(meth, MyClass);
}
Pointing at 'meth' will give a CXCursor_ObjCMessageExpr and pointing at 'MyClass'
will give a CXCursor_ObjCClassRef.
