We aren't expecting to have any numerical limits for bfloat16 type, are we?

This extension doesn't define the bfloat16 as a type, so I think defining the limits for bfloat16 is out of scope of this extension.

@MrSidims
[SYCL] Add BFloat16 aspect
423ff17 
Currently this aspect is mapped on a device info which is
being proved by get_platform_name function, claiming, that any
Intel GPU device supports BFloat16 extension. Once we have
a lower-level spec we can re-map it on the appropriate OpenCL
extension.

Spec:
intel#4237

I notice that the SYCL extension here defines comparison and arithmetic operations, but (1) is named "conversion" in the extension name and (2) the SPIR-V extension includes only conversions. Are math/comparison ops already handled in SPV somehow, and should we rename the SYCL extension to be something more general than "conversions"?

@mkinsner thanks for feedback.

No, we have only conversion in SPIR-V. Math/comparison is done on float type.

should we rename the SYCL extension to be something more general than "conversions"?

Makes sense. Any ideas? SYCL_INTEL_bfloat16?
