clover: Call clang with -O0 for the SPIR-V path

Browse source 
SPIRV-LLVM-Translator isn't really built for handling optimized LLVM IR.
It tends to fall over when, for instance, an optimization generates an
i96 type which isn't legal in SPIR-V.  Pass -O0 to avoid these cases.
See https://github.com/KhronosGroup/SPIRV-LLVM-Translator/issues/203.
