9cd87dbccb Cleanup a bunch of tests. In particular do not allow target directives in
the .ll file or it forces the V9 backend.  This is the CodeGen/Generic dir,
so there is no use in doing that.

18ad19488d Allow the selection-dag based selector to be diabled with -disable-pattern-isel.
For now, this is the default, as the current selector is missing some big pieces.
To enable the new selector, pass -disable-pattern-isel=false to llc or lli.
