[nongnu] elpa/go-mode 385153c 338/495: go.tools/oracle: new query 'referrers' returns all references to an identifier.

[ELPA Syncer]

branch: elpa/go-mode
commit 385153c57e415c45e1ddd5fdb29a2267bdfdbdfb
Author: Alan Donovan <adonovan@google.com>
Commit: Dominik Honnef <dominik@honnef.co>

    go.tools/oracle: new query 'referrers' returns all references to an 
identifier.
    
    + test.
    
    Also:
    - provide non-nil map to Importer.doImport0() to avoid a crash.
    - reorganize oracle "needs" bits.
    - reduce "needs" of 'freevars' and 'implements' queries by avoiding
      ssa.Packages when types.Package suffices.
