 Started with r192219, ended with r203317.  The latter is weird, I thought
 Andrew's patches are just reshuffling of stuff, not changing compiler
 behavior.
 In any case, between r203316 and r203317, pre-unswitch dump the IL is the
 same, unswitching is the first changed dump.

Andrews changes provide accessors that do not compute niter info (you cannot
do that on RTL using the GIMPLE routines).  So if the tree level now uses
those then they need to make sure to compute the info as well.
