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.

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)
- changed sample use in comment to an actually compiled function to make sure
sample is actually working
- added extra tests (checking line and column values, and the tokenize function)

af678a593d new approach for generating sysimport.c 
(renamed to avoid any conflict with old p4 copies).

this approach doesn't require auto-generating
files also kept in p4, so it should be easier on
go users who don't sync very often.

this approach will be more work for go developers:
builtin.c needs to be copied to builtin.c.boot in p4
as new functions are added.  mkbuiltin does this
for certain $USERs to help us remember.

9f726c2c8b Use explicit allspan list instead of 
trying to find all the places where
spans might be recorded.

Free can cascade into complicated
span manipulations that move them
from list to list; the old code had the
possibility of accidentally processing
a span twice or jumping to a different
list, causing an infinite loop.
