<pre>r184928 disables the instrumentation of AllocaInstr with alignment more than
the redzone size (i.e. > 32)
This is a workaround, not a full fix.
Full fix will require to create 256-byte redzones for 256-aligned allocas,
which in turn requires more expensive redzone (un)poisoning.
Since this is an extremely rare case, I am not planing any work on it in near
future.
I'll close this bug now, the larger problem is tracked at
