[flang-commits] [flang] [Flang] Add parsing and attribute registration for SIMPLE specifier (PR #161285)

You need tests that verify that cases in Fortran that require a PURE procedure also work with a SIMPLE procedure.

You need to update the intrinsic procedures that used to be PURE and are now documented as being SIMPLE.
