Error that a pragma is badly formed, when that pragma is defined by IEEE1800-2017.
For example, an empty `pragma line, or an incorrect specified '`pragma protect'.

Warning that a '`pragma protected' section was encountered. The code
inside the protected region will be partly checked for correctness, but is
otherwise ignored.
Suppressing the warning may make Verilator differ from a simulator that
accepts the protected code.
