Previously, the `sycl_kernel_entry_point` attribute could be specified using either the GNU or C++11 spelling styles. Future SYCL attributes are expected to support only the C++11 spelling style, so support for the GNU style is being removed. In order to ensure consistent presentation of the attribute in diagnostic messages, diagnostics specific to this attribute now require the attribute to be provided as an argument. This delegates formatting of the attribute name to the diagnostic engine. As an additional nicety, "the" is added to some diagnostic messages so that they read more like proper sentences.
