[llvm-dev] problem with Value->dump()

[David Blaikie via llvm-dev]

dump functions are only available if LLVM was built with !NDEBUG or with
LLVM_ENABLE_DUMP (so usually a debug build, maybe an Asserts build, not
generally in release builds) - so you might need to find opt built with
this option or build it yourself with this option
