94687acd21 add some abbrevs for ret and unreachable, shrinking kc++ from 2717360->2705388

7a303d1591 enumerate the operands of a constant before we enumerate the constant itself
This avoids fwd references in the reader.

cb3d91b05b add a denser encoding for null terminated strings, add a 6-bit abbrev as
well.  This shrinks kc++ from 2724088 to 2717360 bytes.

817f08a0e5 add an abbreviation for the string constants opzn, shrinking the constnats
block from:

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

d092e0e18f Add abbreviations to the TYPE_BLOCK for pointers, functions, structs and arrays.

ff294a4e1e 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:

e17b658c79 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.

4222d806fa 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.

instead of the default inefficient encoding.  This shrinks kc++ from 4134K
to 3629K

e5b01bea7b Use IntrinsicInst to test for prefetch instructions, which is ever so
slightly nicer than using CallInst with an extra check; thanks Chris.

6da91d3c2c 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.

645fc4edc2 if functiontype is going to have a pointer to a paramattr object, it better
be const.  The only way to get a pointer to these returns a const pointer.

e4b4394b2f 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.
