// 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
