Make a very minor change to the LibVEX_Translate interface (sub-arg of
needs_self_check) which allows VEX's user to selectively override, on
a per-translation basis, the default precise-exception control setting
that is specified in VexControl::iropt_register_updates.  Fix up
plumbing inside iropt so as to used passed-in values rather than the
default one.
