For a number of library functions, the current
tests only check what the compiler does.

Look at this:

$ cat ishft.f90
! { dg-do run }
! verifies basic functioning of the ishft and ishftc intrinsics

$ gfortran -fdump-tree-original ishft.f90
$ cat ishft.f90.t02.original
MAIN__ ()
{
  (void) 0;


$ gfortran -v
Using built-in specs.

We need more test cases that really test the library calls.  Chances
are there may be a few more bugs out there like PR 22142 (which was
also hidden by this).
