Unsure. I'm not 100% convinced that your signbit patch is the
right way to go either. I'm not convinced that exposing this at
the tree level -- at least the way we currently do it, is at all
I can definitely see reusing some of the tree expanders to do
this (e.g. extract_bit_field) instead of playing with subregs
Or we can create some new primitives that aren't so hostile to
the ssa representation. In particular, non-killing sets suck.
