I agree.  Though, I think that you would need to agree with Mark on a
checkin policy after the mainline merge, something like Stage 3 with respect
to compile time (such as, no checkins that slow down the compiler except if
they are not enabled at -O2, or fix regressions?).

Maybe it is just because I came late to the tree-ssa ball, but I'm afraid
wheels have already started spinning (see Honza's work on the tree-profiling
branch).
