Daniel Dunbar a86de10508 MC/Mach-O: Rewrite atom association to be a final pass we do in Finish(), instead of tracking as part of emission.
- This allows sharing more code with the MCObjectStreamer.

Daniel Dunbar 9a744e3860 MC: Add dyn_cast support to MCSection.
- Of questionable utility, since in general anything which wants to do this should probably be within a target specific hook, which can rely on the sections being of the appropriate type. However, it can be useful for short term hacks.

Daniel Dunbar b18d2dd115 MC/Mach-O: Fix some differences in symbol flag handling.
- Don't clear weak reference flag, 'as' was only "trying" to do this, it wasn't
   actually succeeding.
 - Clear the "lazy bound" bit when we mark something external. This corresponds
   roughly to the lazy clearing of the bit that 'as' implements in
   symbol_table_lookup.
 - The exact meaning of these flags appears pretty loose, since 'as' isn't very
   consistent. For now we just try to match 'as', we will clean this up one day
   hopefully.

Daniel Dunbar 525a3a67c1 llvm-mc: Support reassignment of variables in one special case, when the
