cdo 2a3949e09f Make terminal xHEAD and xTAIL registers 32 bits 
This enables waiting on them with memory.atomic.wait32 (there is no
wait8) which is needed to avoid spinning when waiting for a key.

cdo 973eba9f0a Fix NUMBER? 
I wasn't able to keep the length the same so had to update the
addresses of , IMMEDIATE? INTERPRET QUIT and the cold start (and
therefore also the values of LATEST and HERE).

cdo 6474c2f227 Logically flip SPACE? to NSPACE 
WORD was using it like this, and it's easier to fix it this way rather
than insert an INVERT into WORD.

cdo 83022925f7 Fix bugs from round 1 of debugging 
There were several issues I ran into immediately:

- The cold start was pointing to the dictionary entry of QUIT instead
  of the CFA
- The RSP needed to be set before calling QUIT, as DOCOL uses the
  return stack
- I'd forgotten LITs before values in a couple of places
- I'd not accounted for LITs in several branch offsets
- A few dictionary links were wrong
