ABI migration branch for llvm16?

### Comment:

the intel graphics compiler seems to like llvm 16.0.6

does it make sense to build it here?

Start by reading the linked Intel graphics compiler issue and the intel-graphics-compiler and intel-compute-runtime feedstocks. Determine whether an LLVM 16.0.6 ABI migration branch is needed here, which feedstocks would be affected, and what branch or build changes would be required; done means the scope and implementation plan are agreed.
