We need to walk the syntax tree both to find the global aliases that may be in a file, and also to look for attributes.
This change has us walk the green tree instead, especially so we can bail out from checking trees that don't have any attributes, without realizing the red-tree. This save 100MB of ram in incremental testing (About 7.5%).
