 - 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.

With this change, parllc exhibits essentially no overhead on 403.gcc.

doesn't like it.  

Also make the JIT memory manager to initialize it's memory to garbage in debug
mode, so that it's easier to find bugs like these in the future.
