The emutls pass requires PROP_ssa, but if the strubm pass (or any
other pre-SSA pass) issues errors, all of the build_ssa_passes are
skipped, so the property is not set, but emutls still attempts to run,
on targets that use it, despite earlier errors, so it hits the
unsatisfied requirement.
Adjust emutls to be skipped in case of earlier errors.
