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.

SelfRegion represented the object bound to 'self' (when analyzing Objective-C
methods) upon entry to a method. Having this region stored on the side ignores
the current stack frame that we might be analyzing (among other things), and is
a problem for interprocedural analysis.

For RegionStoreManager, the value for SelfRegion is just lazily created.

For BasicStoreManager, the value for SelfRegion is bound eagerly to 'self', but
no explicit tracking of SelfRegion on the side is made.

As part of this change, remove the restriction in BasicStoreManager that we only
track ivars for 'self'. This shouldn't actually change anything in terms of
precision, and simplifies the logic.
