patch against trunk
This patch should be better. It is a FE only change. It stores uses a LANG_FLAG
for each type to store whether it is a VM type which is set during
construction. This should be very efficient. The existing (previously useless)
lang hook then also communicates this information to the middle end. The
variably_modified_p function in tree.cc now does unnecessary work for C, maybe
this could be avoided.
