abfbf85004 further reduce the redundancy of types in the instruction encoding. This
shrinks function bodies in kc++ from 891913B to 884073B

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.

The VST went from:

  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 SubBlocks: 0/0
    Tot/Avg Abbrevs: 7035/3
    Tot/Avg Records: 120924/51.5667
      % Abbrev Recs: 100

to:

  Block ID #14 (VALUE_SYMTAB):

    Tot/Avg Abbrevs: 0/0
    Tot/Avg Records: 120924/51.5667

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

        %tmp = add <8 x i16> %tmp5, %tmp4               ; <<8 x i16>> [#uses=1]
        %tmp6 = bitcast <8 x i16> %tmp to <2 x i64>             ; <<2 x i64>> [#uses=1]
        ret <2 x i64> %tmp6

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.
