[PATCH] WIP Fix for temporary destructors in conditionals

[Jordan Rose]

  Uh...hm. I wouldn't expect this to work because we clean out the environment on the first statement/expression in a basic block. It might be possible to contrive another test case in which the necessary values are not preserved.

  I don't think re-adding values to the Environment is good enough. I think you'll actually have to demonstrate that the BinaryOperators are still live somehow.
