e0b1ee937a Don't attribute in file headers anymore. See llvmdev for the 
discussion of this change.  Boy are my fingers tired. ;-)

93329cbed2 Made Deserializer a friend class of BitstreamReader. 
Moved some of the logic in BitstreamReader::ExitBlock into a utility function
BitstreamReader::PopBlockScope. The latter is a private method. It will also
be called by Deserializer to manipulate the current "block scope."

37779a0b4c we aren't at the end of stream until we've consumed all the bytes AND all 
the bits in those bytes.

eca2bb1334 Implement support for globally associating abbrevs with block IDs, which 
relieves us from having to emit the abbrevs into each instance of the block.
This shrinks kc.bit from 3368K to 3333K, but will be a more significant win
once instructions are abbreviated.

The VST went from:

  Block ID #14 (VALUE_SYMTAB):
      Num Instances: 2345
         Total Size: 1.29508e+07b/1.61885e+06B/404713W
       Average Size: 5522.73b/690.342B/172.585W
          % of file: 48.0645
  Tot/Avg SubBlocks: 0/0
    Tot/Avg Abbrevs: 7035/3
    Tot/Avg Records: 120924/51.5667
      % Abbrev Recs: 100

to:

  Block ID #14 (VALUE_SYMTAB):
      Num Instances: 2345
         Total Size: 1.26713e+07b/1.58391e+06B/395978W
       Average Size: 5403.53b/675.442B/168.86W
          % of file: 47.5198
  Tot/Avg SubBlocks: 0/0
    Tot/Avg Abbrevs: 0/0
    Tot/Avg Records: 120924/51.5667
      % Abbrev Recs: 100

because we didn't emit the same 3 abbrevs 2345 times :)
