The last sentence is unprecise, this would rather be: "Do not call the function
for the memory temporary created for a bitfield".
I wonder whether we should simplify the bitfield case in the process. Once we
remove the call to set_mem_attributes, I think the
/* If the reference doesn't use the alias set of its type,
we cannot create the temporary using that type. */
is useless, so we could try to revert r122014 in the process.
