Vulkan: SPIR-V Gen: Fix precision of findMsb In GLSL, findMsb operates on a highp operand, while returning a lowp result. In SPIR-V, RelaxedPrecision cannot be applied on the FindSMsb instruction as that affects the operand as well. This change makes sure RelaxedPrecision is not applied to a FindSMsb instruction.
