Comment (by Facundo Domínguez <facundo.dominguez@…>):

 Have Core linter accept programs using StaticPointers and -fhpc.

 Summary:
 This patch uses collectArgsTicks instead of collectArgs to test that
 StaticPtr only occurs at the top of RHSs of top-level expressions.

 Ticks introduced by -fhpc would interfere otherwise.

 Test Plan: ./validate
