Nico Weber c3d3f0c696 Add a LLVM_DUMP_METHOD macro. ...

The motivation is to mark dump methods as used in debug builds so that they can
be called from lldb, but to not do so in release builds so that they can be
dead-stripped.

There's lots of potential follow-up work suggested in the thread
"Should dump methods be LLVM_ATTRIBUTE_USED only in debug builds?" on cfe-dev,
but everyone seems to agreen on this subset.

Macro name chosen by fair coin toss.
