    cmd/compile/internal/syntax: compute BranchStmt.Target statements · a5096213
    Robert Griesemer authored
    - Add new BranchStmt.Target field: It's the destination for break,
      continue, or goto statements.
    
    - When parsing with CheckBranches enabled, set the BranchStmt.Target
      field. We get the information practically for free from the branch
      checker, so keep it for further use.
    
    - Fix a couple of comments.
    
    - This could use a test, but the new Target field is currently not
      used, and writing a test is tedious w/o a general tree visitor.
      Do it later. For now, visually verified output from syntax dump.
