Michael J. Spencer 788a6079e1 Fix the msvs 2010 build.
The Microsoft (R) 32-bit C/C++ Optimizing Compiler Version 16.00.30319.01
implements parts of C++0x based on the draft standard. An old version of
the draft had a bug that makes std::pair<T1*, T2*>(something, 0) fail to
compile. This is because the template<class U, class V> pair(U&& x, V&& y)
constructor is selected, even though it later fails to implicitly convert
U and V to frist_type and second_type.

This has been fixed in n3090, but it seems that Microsoft is not going to
update msvc.

John McCall 5ee026c512 Check in a couple of changes that I apparently never committed:
- teach DifferenceEngine to unify successors of calls and invokes
    in certain circumstances
  - basic blocks actually don't have their own numbering;  did that change?
  - add llvm-diff to the Makefile and CMake build systems

John McCall 9ad943ef28 Transcribe IRC to svn. Also don't print basic block names twice if they match.

John McCall 58c5088d48 Switch to using the LLVM CommandLine library so that our help
message is properly contaminated with nonsense about timing passes
that doesn't apply at all to this utility. :)

John McCall eaeede9a06 Centralize the logic to permanently unify two instructions and make sure
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.

John McCall 8489de298e Diagnose non-structural differences in the case where blocks were
structurally identical.

John McCall 0ed6b1326c When unifying instructions during a block diff, actually complain about
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.

John McCall d293c4e6e0 Somehow I was getting reasonable results for the test cases I was interested
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.

John McCall 5e6a16d71f Add the llvm-diff tool, which performs a relatively naive structural
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.
