  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.

  // RewriteExpressionsWithShaderStorageBlock rewrites the expressions that contain shader storage
  // block calls into several simple ones that can be easily handled in the HLSL translator. After the
  // AST pass, all ssbo related blocks will be like below:
  //     ssbo_access_chain = ssbo_access_chain;
  //     ssbo_access_chain = expr_no_ssbo;
  //     lvalue_no_ssbo    = ssbo_access_chain;
  //
  // Below situations are needed to be rewritten (Details can be found in .cpp file).
  //     SSBO as the operand of compound assignment operators.
  //     SSBO as the operand of ++/--.
  //     SSBO as the operand of repeated assignment.
  //     SSBO as the operand of readonly unary/binary/ternary operators.
  //     SSBO as the argument of aggregate type.
  //     SSBO as the condition of if/switch/while/do-while/for
