RFR: JDK-8295406: C1 crash with -XX:TypeProfileArgsLimit=0 -XX:TypeProfileLevel=222

`-XX:TypeProfileArgsLimit=0 -XX:TypeProfileLevel=222` cause an assert to fail in `LIRGenerator::profile_arguments`.

`LIRGenerator::profile_arguments` actually checks if arguments need to be profiled but the `MethodData::profile_arguments` method doesn't take `TypeProfileArgsLimit=0` into account.

Adding a check for _TypeProfileArgsLimit>0_ to determine if arguments have to be profiled.
