Sanjoy Das 9c41a93e24 [FaultMaps] Let the frontend pre-select implicit null check candidates. ...

Summary:
This change introduces a !make.implicit metadata that allows the
frontend to pre-select the set of explicit null checks that will be
considered for transformation into implicit null checks.

The reason for not using profiling data instead of !make.implicit is
explained in the change to `FaultMaps.rst`.
