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.

message is properly contaminated with nonsense about timing passes
that doesn't apply at all to this utility. :)

it establishes a context and does a complaining diff. Also make sure we
unify the prelude and postlude of a diff after a block-diff call.

any differences we see. This should only happen if there are "non-structural"
differences between the instructions, i.e. differences which wouldn't cause
diff to return true.

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.
Patches welcome.

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.

arm explicitly. X86 and ARM are the only two targets that support
disassembly, so our explicit list is enough. These other targets
weren't getting pulled in anyway though, since there were no
references to their symbols.

better in the llvm world. Among other things, this changes:
1. The guts of libedis are now moved into lib/MC/MCDisassembler
2. llvm-mc now depends on lib/MC/MCDisassembler, not tools/edis,
so edis and mc don't have to be built in series.
3. lib/MC/MCDisassembler no longer depends on the C api, the C
API depends on it.
4. Various code cleanup changes.
There is still a lot to be done to make edis fit with the llvm
design, but this is an incremental step in the right direction.
