  [BOLT] Gadget scanner: detect authentication oracles (#135663)

Implement the detection of authentication instructions whose results can
be inspected by an attacker to know whether authentication succeeded.

As the properties of output registers of authentication instructions are
inspected, add a second set of analysis-related classes to iterate over
the instructions in reverse order.
