DO and LOOP now only compile words from stable ABI, which make them suitable for xcomp. This will greatly simplify driver writing and allow us to mostly avoid the low/high divide in drivers. LEAVE is still xcomp-incompatible though. This make us very very tight for "<0x100" limit for literal words. Hopefully, we won't need more stuff in that area of the binary...
