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):
      Num Instances: 1
         Total Size: 139901b/17487.6B/4371.91W
          % of file: 0.549306
        Num Abbrevs: 0
        Num Records: 3203
      % Abbrev Recs: 0

to:
