9d4209fb82 1. Add a pass to fold debug label instructions so a debug info client can detect
empty ranges.

2. Reorg how MachineDebugInfo maintains changes to debug labels.

3. Have dwarf writer use debug label info to simplify scopes and source line
coorespondence.

4. Revert the merging of compile units until I can get the bugs ironed out.

65c5d75bc8 Add a -disable-cbe-printf-a option so that the output of the C Backend
stands a chance of being compiled with a non C99 C compiler. The default
is enabled so you must specifically disable this feature if you want the
CBE output compiled with an older C compiler.

Make necessary changes to support DIV -> [SUF]Div. This changes llvm to
have three division instructions: signed, unsigned, floating point. The
bytecode and assembler are bacwards compatible, however.

Next, remove the constant folding piece of DAGCombiner::SimplifySetCC into
a new FoldSetCC method which can be used by getNode() and SimplifySetCC.
