This patch translates HIP kernels to SPIR-V kernels when the HIP compilation mode is targeting SPIR-S. This involves: * Setting Cuda calling convention to CC_OpenCLKernel (which maps to SPIR_KERNEL in LLVM IR later on). * Coercing pointer arguments with default address space (AS) qualifier to CrossWorkGroup AS (__global in OpenCL). HIPSPV's device code is ultimately SPIR-V for OpenCL execution environment (as starter/default) where Generic or Function (OpenCL's private) is not supported as storage class for kernel pointer types. This leaves the CrossWorkGroup to be the only reasonable choice for HIP buffers. Reviewed By: yaxunl Differential Revision: https://reviews.llvm.org/D109818
