    Message : ES31: support ssbo as binary operand This patch will process ssbo as compound assignment binary operand or readonly binary operand. BUG: angleproject:1951 Change-Id: I4a0da77649d719fa08e6bf4c3d9ace58dbfb7aab Reviewed-on: https://chromium-review.googlesource.com/c/1349449 Commit-Queue: Jiajia Qin <jiajia.qin@intel.com> Reviewed-by: Jamie Madill <jmadill@chromium.org>

// 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
