Tests for Fortran runtime routines do not match spec

[alisterj1138]

The Fortran tests for acc_deviceptr, acc_hostptr, acc_malloc, acc_free, acc_map_data, and acc_unmap_data do not match these routines' descriptions in the spec.

For example, for acc_deviceptr, v3.3 of the spec gives this as the format:

4110 Fortran:
4111 type(c_ptr) function acc_deviceptr(data_arg)
4112 type(*),dimension(*) :: data_arg

While the test seems to be expecting a Fortran pointer, not a c_ptr:

REAL(8), DIMENSION(LOOPCOUNT) :: a, b, c  !Data
REAL(8), POINTER, DIMENSION(:) :: a_ptr, b_ptr, d_ptr

[...]

        a_ptr = acc_deviceptr(a)
        b_ptr = acc_deviceptr(b)
        d_ptr = acc_deviceptr(c)

These tests all likely need to be updated, though it's not always clear (particularly for acc_deviceptr) how to update them while preserving the semantics of the test.
