translator: Add TIntermPreprocessorDirective.

This new node type can be used to inject preprocessor directives into the intermediate tree. Outputting the preprocessor directive is easy for the GLSL back-end. This can be used to implement workarounds such as the OpenGL line rasterization rules on Vulkan. Also fixes the build that was broken on Win/x64 with a prior change and makes more methods in IntermNode.h const.
