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.

NOTE: HLSL row_major and column_major decorations are reversed
      in SPIR-V. Meaning that matrices declrations with row_major
      will get reflected as column_major and vice versa. The
      row and column decorations get appied during the compilation.

      attempt to correct it to match what's in the source.

 @brief  Assign a new location to an output interface variable.
         In addition to updating the reflection data, this function modifies
         the underlying SPIR-V bytecode. The updated code can be retrieved
         with spvReflectGetCode().
         It is the caller's responsibility to avoid assigning the same

         by multiple entry points in the module, it will be changed in all of
         them.
 @param  p_module          Pointer to an instance of SpvReflectShaderModule.
 @param  p_output_variable Pointer to the output variable to update.
 @param  new_location      The new location to assign to p_output_variable.
