  Changed paths:
    M flang/lib/Lower/Bridge.cpp

  Log Message:
  [flang] Add lowering TODO for separate module procedures

MODULE FUNCTION and MODULE SUBROUTINE currently cause lowering crash:
"symbol is not mapped to any IR value" because special care is needed
to handle their interface.

Add a TODO for now.

Example of program that crashed and will hit the TODO:

module mod
    module subroutine sub
    end subroutine
  end interface
  module subroutine sub
    x = 42
  end subroutine
end module

This patch is part of the upstreaming effort from fir-dev branch.
