DTrace: re-merge remainder of r249367 (original from Illumos).

Bring back some important fixes from Illumos:

3022 DTrace: keys should not affect the sort order when sorting by value
3023 it should be possible to dereference dynamic variables
3024 D integer narrowing needs some work

We particularly avoid the LD_NOLAZYLOAD changes that Illumos made
as those don't apply to FreeBSD and were causing problems in
interactive mode.
