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.

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.

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.

ReduceMiscompilingFunctions::TestFuncs. This makes the test functional
(i.e., no side effects).

Before we would end up using dead functions if a pass decided to remove them
(inline for example) and we would also keep broken functions and conclude that
that a single function was enough to reproduce the bug.

disassembly, so our explicit list is enough.  These other targets
