exactly what bugpoint expected it to do.

There was also only one user of
BlockExtractorPass(const std::vector<BasicBlock*> &B), so just remove it and
make BlockExtractorPass read BlockFile.

This fixes bugpoint's block extraction.

Nick, please review.

differences between the instructions, i.e. differences which wouldn't cause

in despite not ever incrementing any path costs, so that the only nonzero costs
arose from the all-left path in the first column.  Anyway.  Perform the diff
starting from the beginning of the block to avoid capturing (say) loads of
allocas.

Vastly improves diff results on code that hasn't been mem2reg'ed.

diff of a function.  There's a lot of cruft in the current version, and
it's pretty far from perfect, but it's usable.

Currently only capable of comparing functions.  Currently ignores metadata.
Currently ignores most attributes of functions and instructions.
