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:

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.
