Nathan Gauër 0e1037edbf [SPIR-V] Strip convergence intrinsics before ISel (#75948) ...

The structurizer will require the frontend to emit convergence
intrinsics. Once uses to restructurize the control-flow, those
intrinsics shall be removed, as they cannot be converted to
SPIR-V.

This commit adds a new pass to the SPIR-V backend which strips those
intrinsics.

Those 2 new steps are not limited to Vulkan as OpenCL could
also benefit from not crashing if a convertent operation is in
the IR (even though the frontend doesn't generate such intrinsics).
