  Changed paths:

    M llvm/lib/IR/Verifier.cpp
    A llvm/test/DebugInfo/X86/assumed_size_array.ll

  Log Message:
  -----------
  [DebugInfo][flang] DISubrange support for fortran assumed size array

This is needed to support assumed size array of fortran which can have missing upperBound/count
, contrary to current DISubrange support.
Example:
subroutine sub (array1, array2)
  integer :: array1 (*)
  integer :: array2 (4:9, 10:*)

  array1(7:8) = 9
  array2(5, 10) = 10
end subroutine
Now the validation check is relaxed for fortran.
