The checkPointerEscape callback previously did not specify how a pointer escaped. This change includes an enum which describes the different ways a pointer may escape. This enum is passed to the checkPointerEscape callback when a pointer escapes. If the escape is due to a function call, the call is passed. This changes previous behavior where the call is passed as NULL if the escape was due to indirectly invalidating the region the pointer referenced. A patch by Branden Archer! llvm-svn: 174677
