Xavier Hallade 1b20a88e97 Fix: Cycles: oneAPI: Performance regression from DPC++ upgrade 
The intel/llvm 7.1 upgrade is giving a large performance regression in
shade_surface kernel on Intel GPUs. I've root-caused it down to a slight
shift in private memory layout due to slightly different inlining.

To fix both this regression and overall performance sensitivity on
private memory layout, that can happen with any code change beyond the
DPC++ upgrade, I'm forcing ShaderData and svm's stack alignments to 64
bytes.
