[This line](https://github.com/ambergorzynski/llvm-project/blob/main/llvm/lib/Target/SPIRV/SPIRVInstructionSelector.cpp#L2454) is untested by the existing test suite (checked using coverage and inserting an `abort` at that line).

We propose a new test for the untested logical `eq` case, similarly to the `neq` case added [here](https://github.com/llvm/llvm-project/commit/e45c8b6555c866cd0412b42fce0439e927ca3ba2).
