IA-64 is using a TImode bitsizetype because it defines 
MAX_FIXED_MODE_SIZE to enable TImode.  The x86_64 port does not, so it 
ends up with a DImode bitsizetype and hence does not have the same 
problem.  It looks like a few other 64-bit ports will fail the same way 
though, like powerpc64 and s390.

We can fix this with small patch to add another bitsizetype conversion 
call.  I'll attach a patch.
