Request: extend SPIRV-Cross to accept OpenCL dialect of SPIR-V..

Hi,
just seeing IWOCL 2019 keynote presentation slides:(https://www.khronos.org/assets/uploads/developers/library/2019-iwocl/IWOCL%20Keynote%20May19.pdf)
https://www.khronos.org/developers/library/2019-iwocl
in page 31 we see talks about possible plans for "OpenCL portability initiative on Apple":
i.e. a OpenCL->Metal shim as Neil mentions that OpenCL maps to Metal better than to Vulkan (for CL->Vulkan we have clvk in progress) and with Apple deprecated OpenCL support maybe of interest..
for that, the slide mentions "SPIR-V Cross would need to be expanded to handle OpenCL dialect of SPIR-V) so just asking here..
I don't know why he doesn't mention using also clspv project which already maps OpenCL C source to SPIR-V Vulkan dialect..
Maybe because project is not mature enough or because maybe because is not enough as OpenCL 2.1 allows feeding directly SPIR-V OpenCL "binary" kernels for which clspv is of not use..
sorry, just random thoughts.. :-)

No source file, test, or entry point is named. Start with the linked IWOCL 2019 keynote, especially page 31, then assess the scope of extending SPIRV-Cross for the OpenCL dialect of SPIR-V. Done would mean a defined implementation plan and demonstrated support for the requested dialect.
