  // RewriteAtomicFunctionExpressions rewrites the expressions that contain
  // atomic function calls and cannot be directly translated into HLSL into
  // several simple ones that can be easily handled in the HLSL translator.
  //
  // We need to rewite these expressions because:
  // 1. All GLSL atomic functions have return values, which all represent the
  //    original value of the shared or ssbo variable; while all HLSL atomic
  //    functions don't, and the original value can be stored in the last
  //    parameter of the function call.
  // 2. For HLSL atomic functions, the last parameter that stores the original
  //    value is optional except for InterlockedExchange and
  //    InterlockedCompareExchange. Missing original_value in the call of
  //    InterlockedExchange or InterlockedCompareExchange results in a compile
  //    error from HLSL compiler.
  //
  // RewriteAtomicFunctionExpressions is a function that can modify the AST
  // to ensure all the expressions that contain atomic function calls can be
  // directly translated into HLSL expressions.
