fd1ae95b8f allow the 8-bit abbrev to be used for either bb or other values

2453f71ae1 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
       Average Size: 5522.73b/690.342B/172.585W

    Tot/Avg Abbrevs: 7035/3
    Tot/Avg Records: 120924/51.5667
      % Abbrev Recs: 100

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

5969830361 where possible, encode symtab names with 7 bits per char instead of 8. This
shaves 110K off kc++ to 3514K.  Before:

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.

c453f76e2b Switch the bitcode reader interface to take a MemoryBuffer instead of knowing
anything about disk I/O itself.  This greatly simplifies its interface -
eliminating the need for the ReaderWrappers.cpp file.

This adds a new option to llvm-dis (-bitcode) which instructs it to read
the input file as bitcode.  Until/unless the bytecode reader is taught to
read from MemoryBuffer, there is no way to handle stdin reading without it.

I don't plan to switch the bytecode reader over, I'd rather delete it :),
so the option will stay around temporarily.
