RFR: 8332394: Add friendly output when @IR rule missing value [v2]

[Hamlin Li]

> Hi,
> Can you help to review this simple patch?
> Currently, when a @IR rule like "applyIfPlatform" or "applyIfCPUFeature" miss a value, it will just throw ArrayIndexOutOfBoundsException, with no other information. This is confusing unless you dig into the test frame code.
> It's helpful to output more meaningful information.
> Thanks
