This patch augments the HIPAMD driver to allow it to target AMDGCN flavoured SPIR-V compilation. It's mostly straightforward, as we re-use some of the existing SPIRV infra, however there are a few notable additions: - we introduce an `amdgcnspirv` offload arch, rather than relying on using `generic` (this is already fairly overloaded) or simply using `spirv` or `spirv64` (we'll want to use these to denote unflavoured SPIRV, once we bring up that capability) - initially it is won't be possible to mix-in SPIR-V and concrete AMDGPU targets, as it would require some relatively intrusive surgery in the HIPAMD Toolchain and the Driver to deal with two triples (`spirv64-amd-amdhsa` and `amdgcn-amd-amdhsa`, respectively) - in order to retain user provided compiler flags and have them available at JIT time, we rely on embedding the command line via `-fembed-bitcode=marker`, which the bitcode writer had previously not implemented for SPIRV; we only allow it conditionally for AMDGCN flavoured SPIRV, and it is handled correctly by the Translator (it ends up as a string literal) Once the SPIRV BE is no longer experimental we'll switch to using that rather than the translator. There's some additional work that'll come via a separate PR around correctly piping through AMDGCN's implementation of `printf`, for now we merely handle its flags correctly.
