Vulkan: Direct SPIR-V Gen: Support the precise keyword The precise keyword is different in GLSL in that it defines what arithmetic operations _that have led to the value being assigned to a variable_ should be done precisely (i.e. not "contracted"). A tree traverser is implemented that detects precise access chains and applies precise-ness to the right hand side of assignment expressions to said access chains. This is only done if the shader uses the precise keyword in the first place. The algorithm for this is inspired by the implementation in glslang. This change additionally: - Fixes parser to allow precise on function parameters - Fixes GLSL code generation to output precise on struct members and function parameters.
