If the calling function had more target features enabled than the callee than the attribute wasn't being applied as the arguments for the check had been swapped round. Also includes target features that are part of the global set as the warning was checking those but when adding the attribute they were not checked. Add a codegen-llvm test to check that the attribute is actually applied as previously only the warning was being checked.
