  // 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
