Chris Lattner a3a0681083 Enhance llvm::SourceMgr to support diagnostic ranges, the same way clang does. Enhance 
the X86 asmparser to produce ranges in the one case that was annoying me, for example:

test.s:10:15: error: invalid operand for instruction
movl 0(%rax), 0(%edx)
              ^~~~~~~

It should be straight-forward to enhance filecheck, tblgen, and/or the .ll parser to use 
ranges where appropriate if someone is interested.

Renato Golin 4b6ae939ca This patch is a big refactoring of llvm-diff. It doesn't add new features, but it re-organizes the old features, so I can insert the MetadataEngine to use the same infrastructure.

Chris Lattner accb015f7c cleanups: mark stuff static, only tagdecls should be in anon namespaces.

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 61483f0e1f Make the header self-contained and follow #include guidelines.

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 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.
