The element type parameter, _DataT_, must be one of the basic scalar types
supported in device code.

The SYCL [code]#vec# class template provides interoperability with the
underlying vector type defined by [code]#vector_t# which is available only when
compiled for the device.
The SYCL [code]#vec# class can be constructed from an instance of
[code]#vector_t# and can implicitly convert to an instance of [code]#vector_t#
in order to support interoperability with native <<backend>> functions from a
SYCL kernel function.

An instance of the SYCL [code]#vec# class template can also be implicitly
converted to an instance of the data type when the number of elements is
[code]#1# in order to allow single element vectors and scalars to be convertible
with each other.
