Teresa Johnson 6794d96976 Restore "[WPD/LowerTypeTests] Delay lowering/removal of type tests until after ICP" 
This restores commit 80d0a137a5aba6998fadb764f1e11cb901aae233, and the
follow on fix in 873c0d0786dcf22f4af39f65df824917f70f2170, with a new
fix for test failures after a 2-stage clang bootstrap, and a more robust
fix for the Chromium build failure that an earlier version partially
fixed. See also discussion on D75201.
