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.

...
by 40%, FreeBench/fourinarow by 20%, and many other programs 10-25%.
On PPC, this speeds up fourinarow by 18%, and probably other things as well.
