  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.

  // DeferGlobalInitializers is an AST traverser that moves global initializers into a separate
  // function that is called in the beginning of main(). This enables initialization of globals with
  // uniforms or non-constant globals, as allowed by the WebGL spec. Some initializers referencing
  // non-constants may need to be unfolded into if statements in HLSL - this kind of steps should be
  // done after DeferGlobalInitializers is run. Note that it's important that the function definition
  // is at the end of the shader, as some globals may be declared after main().
  //
  // It can also initialize all uninitialized globals.
