parser: Require SystemVerilog for implicit named port connections 

Implicit named port connections are only supported by SystemVerilog. Add a
check to generate an error when trying to use it in Verilog mode.

Regression test br_gh315 is modified to run in SystemVerilog mode since it
makes use of implicit named port connections.
