[tree-ssa] USE or VUSE bugs?

[Wei Liu]

Thank you for Diego and Daniel's help.

Eventually I figured out when I compile it with option
-fno-strict-aliasing and -ftree-points-to=anderson together, it will have
the problem. So after remove -fno-strict-aliasing, everything looks fine
to me.

I'm still not sure why using these two flags together may cause problems.
If these two can not be used together, it would be nice if the compile can
throw out a warning or error info.

thanks.
