Make LD_DEBUG more user-friendly.

This is more self-explanatory than arbitrary integers, actually does
explain itself if you typo or say LD_DEBUG=help, and makes statistics
and timing available without recompilation.

Some of the groups could probably use a little tweaking, and we could
probably use some more groups, but I think this is already better than
what we have, and the initial change moving LD_DEBUG from integers to
names should probably minimize the amount of change that regard.

There's also the continuing question of whether statistics and timing
should just be deleted. They're not super useful as-is, and we should
think about whether we want to make them more useful or just remove them.
The timing stuff in particular is probably questionable, because
systrace is probably a better way to do anything like that? But that too
sounds like a question for another day.
