Nicolai Haehnle f3907ede55 AMDGPU: Fix use-after-free in SIOptimizeExecMasking ...

Summary:
There was a bug with sequences like

   s_mov_b64 s[0:1], exec
   s_and_b64 s[2:3]<def>, s[0:1], s[2:3]<kill>
   ...
   s_mov_b64_term exec, s[2:3]

because s[2:3] was defined and used in the same instruction, ending up with
SaveExecInst inside OtherUseInsts.

Note that the test case also exposes an unrelated bug.
