<pre>
    Add a way in clang to control version of SPIR-V binary being emitted.

This should just be as simple as forwarding a flag to `llvm-spirv` or native backend in the future.
https://clang.llvm.org/docs/UsersManual.html#spir-v-support

Example use of llvm-spirv with version control:
`llvm-spirv --spirv-max-version=1.3 test.bc`

Note that how exactly this version is specified should be discussed, some alternatives are:
- use separate value in triple
- use separate flag
