Word types

There are 4 word types in Collapse OS. Whenever you have a
wordref, it's pointing to a byte with numbers 0 to 3. This
number is the word type and the word's behavior depends on it.

0: native. This words PFA contains native binary code and is
jumped to directly.

1: compiled. This word's PFA contains an atom list and its
execution is described in "EXECUTION MODEL" above.

2: cell. This word is usually followed by a 2-byte value in its
PFA. Upon execution, the address of the PFA is pushed to PS.

Make word routines into word types Instead of having wordref point to core word routines, I made them into word 4 word types. It liberates space into the stable ABI and should make porting to other arches easier. I'm also thinking of combining word type with the namelen field for precious bytes saving, but not now... 2020-06-17 21:41:01 -04:00			`Word types`
