Vl-gatedelay-wildelim

Eliminate ==? and !=? operators throughout a vl-gatedelay-p

Signature
(vl-gatedelay-wildelim x ctx warnings) → (mv warnings new-x)
Arguments: x — Guard (vl-gatedelay-p x).; ctx — Guard (vl-context-p ctx).; warnings — Guard (vl-warninglist-p warnings).
Returns: warnings — Type (vl-warninglist-p warnings).; new-x — Type (vl-gatedelay-p new-x).
