Zachary Turner dd3a739d52 [CodeView] Add a random access type visitor.
This adds a visitor that is capable of accessing type
records randomly and caching intermediate results that it
learns about during partial linear scans.  This yields
amortized O(1) access to a type stream even though type
streams cannot normally be indexed.
