// 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
