Subject: Add support for vector/scalar compares for GLSL (#903)

* * leftSide and rightSide set op to nullptr, before was just uninitialized
* Added support for GLSL for vector/scalar comparisons
* Added test

* * Remove unneeded precedence code.
* Simplify function to _maybeEmitGLSLCast

* * Take into account precedence & closing of brackets in same way as function call, if function call used for vector comparison (as on GLSL)
