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.

d8ba292c9b Fixed the problem with a branch to "0b" that was not parsed by llvm-mc 
correctly.  The Lexer was incorrectly eating the newline casusing it to branch
to address 0.  Updated the test case to use a "0:" label and a branch to "0b".

9a744e3860 MC: Add dyn_cast support to MCSection.

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.

61066dbdf2 MC: Switch to using explicit MCAlignFragments with OnlyAlignAddress bit instead

    - This probably seems like six-of-one and half-dozen of another, but there
      is a method to my madness.

456b501270 MC: Add MCAlignFragment::OnlyAlignAddress bit. This is a bit of magic that says the align fragment shouldn't contribute to the logical section size, it is will be used for cleaning up the code to handle section alignment.
