  Translator: Allow tree validation in children of TCompiler
  
  This is to be able to perform validation inside TranslatorVulkan, even
  if it's through ASSERTs.
  
  Additionally, every transformation is changed such that they do their
  validation themselves.  TIntermTraverser::updateTree() performs the
  validation, which indirectly validates many of three tree
  transformations.  Some of the more ancient transformations that don't
  use this function directly call TCompiler::validateAST.

  // RewriteCubeMapSamplersAs2DArray: Change samplerCube samplers to sampler2DArray, and the
  // textureCube* function calls to calls to helper functions that select the cube map face and sample
  // from the face as a 2D texture.  This emulates seamful cube map sampling in ES2 (or desktop GL 2)
  // and therefore only looks at samplerCube (i.e. not integer variants or cube arrays) and sampling
  // functions that are defined in ES GLSL 1.0 (i.e. not the cube overload of texture()).
