Make tail merging the default, except on powerPC. There was no prior art
...
for a target-dependent default with a command-line override; this way
should be generally usable.

Split the addPassesToEmitFile method up into two. This is so that we can
...
do some common stuff, then on our own add an object file writer (by calling
a concrete function), and then do some finishing stuff, if need be.

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.

add the branch folding pass as a late cleanup pass for all targets. For now
...
it just deletes empty MBB's. Soon it will do more :)
