This adds -no-opaque-pointers to clang tests whose output will
change when opaque pointers are enabled by default. This is
intended to be part of the migration approach described in
https://discourse.llvm.org/t/enabling-opaque-pointers-by-default/61322/9.
The patch has been produced by replacing %clang_cc1 with
%clang_cc1 -no-opaque-pointers for tests that fail with opaque
pointers enabled. Worth noting that this doesn't cover all tests,
there's a remaining ~40 tests not using %clang_cc1 that will need
a followup change.

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.
