Re-land of #116636 Adds a new address spaces: hlsl_private. Variables with such address space will be emitted with a Private storage class. This is useful for variables global to a SPIR-V module, since up to now, they were still emitted with a Function storage class, which is wrong. --------- Signed-off-by: Nathan Gauër <brioche@google.com>
