[RFA/RFC patch]: Follow-up on type-demotion pass ...

[Joseph S. Myers]

This is not a review, but:

* What do you need from rtl.h?  It's generally best for GIMPLE passes to 
avoid rtl.h where possible (and if you can avoid it, the next question is 
whether you can also avoid tm.h).

* Going just on the general description of the pass and not looking at the 
details: does this do any of the things that are done by shorten_binary_op 
or shorten_compare in c-common.c?  If so, do you plan followup changes to 
remove as premature optimizations whatever those functions do that can be 
done by this pass?
