Feeding libclang with unsaved files (e.g. in-memory generated ui_*.h)
that do not exist on disk leads to regeneration of the preamble on every
parse/reparse/completion and thus renders the clang code model useless.
We could check the existence in the file system for every unsaved file
just before every parse/reparse/completion. Obviously this does not
scale (e.g. qtcreator.pro generates about 200 unsaves files) and would
also slow down the responsiveness of the completion, especially for the
dot-to-arrow correction case.
We could also set up a file system watcher. However, implementing the
"file got created" case is not trivial because QFileSystemWatcher does
not support it out of the box.
Instead, set up a custom include directory and create empty files in it
that represent the unsaved files and pass that include directory to
libclang as the last one. While this fixes the performance problems, it
also comes with at least two problems:
* Because ui_*.h files are "relocated" to the same directory, two or
more "foo.ui" in the same session will be problematic.
* Because of the custom include directory, problems might arise for
projects that include the ui_*.h as "some/relative/path/ui_foo.h"
instead of "ui_foo.h". This should be the less common case.

1 struct Foo { int member; };
2 void f(Foo *foo)
3 {
4 foo.<REQUEST COMPLETION> // correct '.' to '->' and provide results
5 }
The preferred approach would be to check if "foo" in line 4 is of
pointer type, but there is no suitable cursor (only CompoundStmt) at
that position since the code is usually not yet parsed and thus invalid.
Thus, just run the completion as is. If there are not any results for a
dot completion, re-run the completion with "." exchanged by "->". This
approach is inherently slower than the preferred approach implemented in
the built-in code model.
The following rare cases are not handled:
1) Requesting completion after white space:
Works: foo.<COMPLETE HERE>
Fails: foo. <COMPLETE HERE>
2) Opening a file and requesting completion (ctrl+space) without prior
editing. No editing before triggering completion means that no
unsaved file is generated on the backend side, which is a
requirement for the correction.
