I looked up what the state of always_ff, always_latch, and always_comb
are in Icarus git master.

They are present and accounted for as language-level-specific keywords
in lexor_keyword.gperf and parse.y.  But parse.y never uses them in
in the grammar.

Adding them to the grammar would be easy -- even I could do that.
But then Icarus would need new enum values for ivl_process_type_e,
and handle their semantics correctly.  This has to be done without
breaking the old "always" semantics.

Good thing we have ivtest!
