Detailed Description

The inspector builds a map of aliased fields (IR::BFN::AliasMember) mapping alias destinations to their sources. Only aliases with destinations annotated with the @flexible annotation are considered.

Logging options
-Tbridged_packing:5	The aliases being added to the map Notice when a field is marked bridged in PhvInfo and is not included in the CollectIngressBridgedFields::bridged_to_orig map

Precondition: The Alias pass needs to be performed before this one to create IR::BFN::AliasMember IR nodes. TODO: We could figure out the mapping from def-use analysis instead.
