Where is the fire?

Can you please add a comment here explaining that many MIPS targets do 
not yet use this method because they are still defining the macro.

As a separate patch, could you please update things so that:

This returns ieee_double big/little.

This returns builtin_type_uint64.

This returns builtin_type_uint32.
