Currently on s390x, tan assembly implementation is not handling huge arguments at all. This change is to check for large arguments and revert back to native go implantation from assembly code in case of huge arguments. The changes are implemented in assembly code to get better performance over native go implementation. Benchmark details of tan function with table driven inputs are updated as part of the issue link.
