It is possible to use an LSP to determine which code is used, at least
to some degree.
Make a start on this, in the hope that future work may prove out the
concept.
So far I have not found this to be particularly useful, since it does
not seem to handle IS_ENABLED() and similar macros when working out
inactive regions.
