convert 386 to use %gs instead of %fs for extern register.
...
required for nacl and may be nicer for ffi,
because %gs is the standard register for thread-local storage.

compilers were inconsistent about
...
whether no register argument was
REGARG == 0 or REGARG < 0.
use REGARG < 0 because arm needs 0 for R0.

and make 5c, 8c use them.
centralizes reachability analysis
and switch generation.

use cc provided xlog2 instead of system log2.
...
(on plan 9 cc calls it log2, but that conflicts here.)
the difference is that xlog2 returns -1 on non powers of 2.
8c was rewriting /10 into /8.

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.
