Chris Lattner d092e0e18f 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:

  Block ID #10 (TYPE_BLOCK):
      Num Instances: 1
         Total Size: 99389b/12423.6B/3105.91W

        Num Abbrevs: 4
        Num Records: 3203
      % Abbrev Recs: 99.6566
