Summary:
Depends on D21065. Ref T13492. Swap existing "expect" blocks from unstable, unreadable JSON to readable, stable trees.
(There are two "INVALID TYPE" outputs which this update effectively detects and which future changes correct.)
Test Plan: Ran "arc unit --everything", got a clean build.
Maniphest Tasks: T13492
Differential Revision: https://secure.phabricator.com/D21066
Summary: Ref T13395. Moves all remaining code in "libphutil/" into "arcanist/".
Test Plan: Ran various arc workflows, although this probably has some remaining rough edges.
