[VM] Bare instructions - Part 3: Add support for building a PC -> Code mapping table This CL adds a [ReversePcLookupCache] which, based on a list of code objects, builds up a binary searchable table for mapping PCs to Code objects (where all the metadata is available, like stackmaps, ...). This CL also adds stack walking support for "bare instruction" frames. In a later part we will start emitting the sorted list of code objects (via the new field in the object store) under a flag.
