[PATCH] [dwarfdump] Pretty print location expressions and location lists

[Frederic Riss]

I could commit the DWARFDebugLoc refactoring (without the pretty printing) separately, but this is about all that can be split out. This patch really has 4 parts that are reviewable separately (but that don't really make sense as separate):

- The refactoring in DWARFDebugLoc.{cpp/h}: This I could commit separately leaving the new pretty-printing out.
- The new DWARFExpression.cpp/h}: The bulk of the patch logic. Pretty self contained it interacts with the outside world through just 1 function. Can be reviewed separately.
- The integration into the DIE/DebugLoc dumpers.
- The tests updates.

Leaving out the DWO case would spare maybe 10 lines, I don't think this will really make it more digestible for you...
