Hi!
This tiny patch moves ASan and TSan passes just before sanopt pass,
that gives nice speedup on several SPEC2006 tests (-O2 optimization
level was used) on x86:

Does this change looks reasonable for trunk?

I've rechecked testing results and found out, that such huge speedup in
appropriate tests was caused by missing instrumentation of
TARGET_MEM_REFs. After fixing this, all speedup gone, so moving ASan
pass down to pipeline doesn't make any sense. Sorry for noise.
