2bd101c4b1 update 8a, 8c, 8l to use new object format. 
add "extern register" support to 8c.
extern register means allocate in the FS-relative segment.

make 8l generate segmented stack checks.

(per discussion w/ Russ)
- use explicit nodes for various language constructs for better readability

6f321e28f4 - remove special handling of '\n' characters (used to be treated as comments 
for pretty printer purposes - now properly ignored as white space since we
have line/col information)

sample is actually working
- added extra tests (checking line and column values, and the tokenize function)
