/*! @enum SpvReflectModuleFlagBits

SPV_REFLECT_MODULE_FLAG_NO_COPY - Disables copying of SPIR-V code 
  when a SPIRV-Reflect shader module is created. It is the 
  responsibility of the calling program to ensure that the pointer
  remains valid and the memory it's pointing to is not freed while
  SPIRV-Reflect operations are taking place. Freeing the backing 
  memory will cause undefined behavior or most likely a crash.
  This is flag is intended for cases where the memory overhead of
  storing the copied SPIR-V is undesirable.
