    Remove CONSTR_STATIC · 55d535da
    Simon Marlow authored
    We currently have two info tables for a constructor
    * XXX_con_info: the info table for a heap-resident instance of the
      constructor, It has type CONSTR, or one of the specialised types like
    * XXX_static_info: the info table for a static instance of this
      constructor, which has type CONSTR_STATIC or CONSTR_STATIC_NOCAF.
    I'm getting rid of the latter, and using the `con_info` info table for
    both static and dynamic constructors.  For rationale and more details
    see Note [static constructors] in SMRep.hs.
    I also removed these macros: `isSTATIC()`, `ip_STATIC()`,
    `closure_STATIC()`, since they relied on the CONSTR/CONSTR_STATIC
    distinction, and anyway HEAP_ALLOCED() does the same job.
    Test Plan: validate
