clang/AMDGPU: Remove driver restriction on --gpu-max-threads-per-block
Previously this flag was only handled for HIP, and would produce an unused
argument warning. There is a custom warning produced by cc1 that the
argument isn't supported, but practically speaking that was unreachable
due to not forwarding the argument. Also add a test for the untested warning.
Also use a simpler method for forwarding the flag to cc1.

clang/AMDGPU: Merge toolchain subclasses
Simplify the toolchain implementations by collapsing
them into one. Previously we had a confusing split. The
AMDGPUToolChain base class implemented much of the base
support. It was subclassed by ROCMToolChain, which would
have been more accurately described as the offloading subclass.
That was further subclassed into HIP and OpenMP specific subclasses.
Deleting those two is the important part of this change. There was
code duplication, and features arbitrarily handled in one but not
the other. The offload kind is passed in almost everywhere if you
really need to know the original language. However, I consider
this an antifeature, and it is really poor QoI to have the HIP
and OpenMP toolchains behave differently in any way. The platform
should be consistent and the driver behaviors should not depend
on the language.
There is additional mess in the handling of spirv, which this

clang/AMDGPU: Fix double linking opencl libs with --libclc-lib
Noticed by inspection. If using an explicit --libclc-lib flag,
do not attempt to also link the rocm device libs which will contain
different implementations of the same opencl symbols.
