[PATCH] D94013: [libclc] Add clspv target for libclc

> The FMA does pass conformance. I don't have performance numbers for the 64-bit version vs the uint2 version. It would be worse, but the whole  software FMA is already awful performance. The 64-bit version is simpler to understand, so unless you have the same restrictions as I need for clspv, then I wouldn't adopt it.

There are existing `spirv` and `spirv64` targets. The new `clspv` target uses the same `spir--` triple as `spirv`, but doesn't use the final spv conversion step and uses O3 <https://reviews.llvm.org/owners/package/3/> optimization. The selection of files is mostly a subset of the existing `spirv` target.
