 - Prefer short-imm instructions over ext-imm, when possible
 - Prefer Z10 instructions over Z9, when possible

This hopefully should fix some dejagnu test fails on solaris

 - Honor .globl.

 - Set symbol type and section correctly ('nm' now works), and order symbols
   appropriately.

 - Take care to the string table so that the .o matches 'as' exactly (for ease
   of testing).

 - The only .s syntax this honors right now is emitting labels, and some parts
   of the symbol table generation are wrong or faked.

 - This is enough to get nm to report such symbols... incorrectly, but still.

Also, fixed byte emission to extend the previous fragment if possible.

(external was really undefined and there wasn't an explicit representation for
absolute symbols).
 - This still needs some cleanup to how the absolute "pseudo" section is dealt
   with, but I haven't figured out the nicest approach yet.

to ensure that at least one write has completed before return the pointer into it.

 - Just emit a .align when we see the directive; this isn't exactly what 'as'
   does but in practice it should be ok, at least for now. See FIXME.
