Chris Lattner 4b6ce8fa59 add an abbreviation for the string constants opzn, shrinking the constnats 
block from:

  Block ID #11 (CONSTANTS_BLOCK):

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

Chris Lattner ccee706345 Add abbreviations to the TYPE_BLOCK for pointers, functions, structs and arrays. 
This shrinks the type_block of kc++ from 139901 bits to 99389 bits (0.55% to 0.39%
of the file), a 40% reduction.

This shrink the record from:

  Block ID #10 (TYPE_BLOCK):

Chris Lattner e760d6f4c1 add a char6 abbrev for bbnames and value names. This represents each character 
with 6 bits where possible.  This shrinks kc++ from 3324164B to 3183584B.  The
old VST was:

  Block ID #14 (VALUE_SYMTAB):
         Total Size: 1.26713e+07b/1.58391e+06B/395978W
       Average Size: 5403.53b/675.442B/168.86W
          % of file: 47.6484

The new one is:

  Block ID #14 (VALUE_SYMTAB):
         Total Size: 1.15467e+07b/1.44334e+06B/360834W
       Average Size: 4923.96b/615.495B/153.874W
          % of file: 45.3368

This is 11% smaller than the VST in the bytecode format.
