[flang] Don't complain about implicitly-typed dummy arguments inherit…
…ed into an IMPLICIT NONE submodule When a module procedure's interface is defined in an ancestor (sub)module with an implicitly typed dummy argument, don't emit a bogus error in the separate module procedure later if its submodule has IMPLICIT NONE. Fixes llvm-test-suite/Fortran/gfortran/regression/submodule_26.f90. Differential Revision: https://reviews.llvm.org/D157335
