277c22f0a9 add an abbreviation for the type symtab, this shrinks the TST from 175197 bits 
to 103165 bits:

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):

         Total Size: 1.29508e+07b/1.61885e+06B/404713W

to:

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

b94c8f4ed8 shave another 150K off of kc++, by using a 7-bit encoding for BB names 
where we can.  This shrinks kc++'s down to 3368K, with a VST record of:

  Block ID #14 (VALUE_SYMTAB):
      Num Instances: 2345
         Total Size: 1.29508e+07b/1.61885e+06B/404713W

Isn't it nice to be able to optimizer bc size without touching the reader? :)

2eaf2a2e40 where possible, encode symtab names with 7 bits per char instead of 8. This

dc82c5a195 Add an "implies" field to features. This indicates that, if the current 
feature is set, then the features in the implied list should be set also.
The opposite is also enforced: if a feature in the implied list isn't set,
then the feature that owns that implies list shouldn't be set either.

ddc5d5ce50 optimize constant layout. This fixes encoding of 181.mcf (by ensuring 
integer structure idx's are emitted before constant expr geps) and shrinks
files slightly.  For example kc++ shrinks from 4326188 to 4240128 bytes.

be const.  The only way to get a pointer to these returns a const pointer.

68ab99ffb6 Bitcast all the bits of a floating point value, not just one. The zero 
extension is needed because the constructor for the Destination value
causes the APInt to have a bit width of 1.
