From 58f3877307afd8c07fdad680eb09c0f2771a3240 Mon Sep 17 00:00:00 2001

Subject: Add a new pass AddReadAttrs which works out which functions can get
the readnone/readonly attributes, and gives them it. The plan is to remove
markmodref (which did the same thing by querying GlobalsModRef) and delete
the analogous functionality from GlobalsModRef.
