Bug description:
Tracking bug for the application of the retpoline hint tracking
support.
We are having terrible trouble with hints changing on every build.
Upstream is moving to hinting those indirections which have been
reviewed and are good. This includes direct hinting of PVOPS and the
like which are the ones which change all the time as new ones appear
and dissappear.
Backport the hint support and add our own bespoke checkers against
this data.
