Log Message:
1.0.10.7: multiply-used DX LVARS

* HANDLE-NESTED-DYNAMIC-EXTENT maps over all the uses of the LVAR,
  collecting their argument lvars as well.

* RECHECK-DYNAMIC-EXTENT-LVARS accepts multiply-used DX LVARs,
  checking that all uses support stack allocation.

* UPDATE-UVL-LIVE-SETS accepts multiply-used DX LVARs, doing that
  lifetime merging with all uses.

* ...and OOPS, move the NEWS entries of .5 and .6 to a new section for
  1.0.11...
