This patch adds a needs_unsafe_ldstex to runsuite.cmake and runsuite_wrapper.pl. It adds '-unsafe_build_ldstex' to TEST_OPTIONS and selects a bigger list of failing tests with the option.
We also have to change the order TEST_OPTIONS are added to dr_ops, otherwise -unsafe_build_ldstex is added to late and not picked up.
Issue #1698
