As Jeff said, most of the discussions to date have centered on the
new mid-level IR being an idealized form of RTL, without all of the
CLOBBER, cc0, etc. baggage.
The very broad view, as far as I understand it, would move some
optimizations into the tree phase, then drop down into the mid-level IR
and SSA optimizations, then introduce more of the machine dependencies of
the current RTL and the current optimizations which still are relevant.
