This doesn't DTRT with the old attribute, because you lookup_attribute only the
new name.
Either you'd need to look up also the old name, or
handle_no_address_safety_attribute would need to add the new name of the
attribute manually (and perhaps don't add the old name).

I can take care of it (and perhaps also introduce no_sanitize_thread attribute
- what exactly should be done when it is set?  Instrument atomics always, and
not instrument anything else?).

OT, are you ok with incrementing the kMidMemEnd value (see my mail from Friday
last week)?
