This is a generic tool to convert OpenCL C to SPIR-V.
In the future, this will be replaced by `clang` directly using the LLVM SPIR-V
backend, but for now we need a tool in Mesa to provide this functionality with
older LLVM versions.
The important parts are that:
1. It does not depend on NIR or any real platform details. An older mesa_clc
from a previous Mesa version can generally be used to build a newer Mesa to
ease cross-OS builds.
2. Its output can be consumed without any LLVM dependence, which will untangle
the LLVM mess we have now.
