argh! conflicts!

including I noticed

what is this with part of FastTypes being split off into FastBool?
   * Fix warnings in utils/FastTypes
   Split off a FastBool module, to avoid a circular import with Panic

FastTypes doesn't import Panic
although
compiler/main/TidyPgm.lhs:import FastBool hiding ( fastOr )
compiler/nativeGen/MachCodeGen.hs:import FastBool               ( 
isFastTrue )
compiler/nativeGen/RegAllocInfo.hs:import FastBool
compiler/nativeGen/MachRegs.lhs:import FastBool

oh, darnit, you wanted to panic for invalid FastBools... which seems 
reasonable and hard to work around.  (although: if the code typechecks 
with FastBool=Bool, then I don't think it's possible to happen? Or do 
ghci / GHC API make it more complicated? yes I guess they do.)

Alright, I suppose there's no problem supporting FastBool, just more 
amending attempts
