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

88e78f8bdb 3DNowA implies 3DNow. 64-bit implies SSE1, SSE2, and I assume MMX.

11ca4f51ed Remove the -emit-bytecode option. Noone in the llvm tree uses it, and this 
keeps llvm-upgrade a simple "source to source" tool.

50460e7c48 enumerate the operands of a constant before we enumerate the constant itself 
This avoids fwd references in the reader.

6d0c5eb739 add a denser encoding for null terminated strings, add a 6-bit abbrev as 
well.  This shrinks kc++ from 2724088 to 2717360 bytes.

63002bb235 add an abbreviation for the string constants opzn, shrinking the constnats 
block from:

  Block ID #11 (CONSTANTS_BLOCK):
      Num Instances: 1722
         Total Size: 3.85976e+06b/482470B/120617W
          % of file: 16.7609
       Average Size: 2241.44b/280.18B/70.045W
  Tot/Avg SubBlocks: 0/0
    Tot/Avg Abbrevs: 1/0.00058072
    Tot/Avg Records: 26423/15.3444
      % Abbrev Recs: 69.1746

to:

 Block ID #11 (CONSTANTS_BLOCK):
      Num Instances: 1724
         Total Size: 2.62406e+06b/328008B/82001.9W
          % of file: 12.041
       Average Size: 1522.08b/190.26B/47.5649W
  Tot/Avg SubBlocks: 0/0
    Tot/Avg Abbrevs: 2/0.00116009
    Tot/Avg Records: 26280/15.2436
      % Abbrev Recs: 68.9992

This shrinks kc++ from 2815788 to 2724088 bytes, which means the bitcode
file is now smaller than the bytecode file.

32d91f39ca stop encoding type/value pairs when the type is implied by the value.
