[SYCL] Use of Unified Shared Memory #283

Closed Michoumichmich closed 3 years ago

Michoumichmich commented 3 years ago

This PR changes the GPU backend to use USM instead of sycl::buffers that can lead to implicit data movements. This allows also to use the same interface for the c-sycl_intel target. It also addresses the FIXME comment given that we can allocate "void" memory.
