[PATCH] Fixing a heisenbug where the memory dependence analysis behaves differently with and without -g

[Manman Ren]

Hi Yunzhong,

A few nits:

In the file name "inst_limits.ll", we prefer "-" instead of "_".

+      // Debug intrinsics don't (and can't) cause dependences.
--> dependencies

I agree with David that you should only need one dbg.value intrinsic to
show the problem.

Thanks for working on this,
Manman
