GlobalISel currently does not implement support for blockaddress which makes it
fallback to SelectionDAGISel. This generates different code than FastISel with
branch instructions to the very next address. As a result some OMPT tests were
failing because they don't expect the additional instructions. To workaround
that problem we have disabled GlobalISel for now but it would be good to
implement proper support and remove that hack.
