It's hard to predict that.  Compilers often align variables to start on
word boundaries anyway, so, memory usage would be the same if that was done.
For variables which don't exist on a word boundary, you need to do a shift
after loading the word into a register, which is why compilers tend not
to use them.

The only common 64 bit systems that I know of are the Alpha and the
Ultrasparc.  Both of these systems support 64 bit arithmetic.  I don't know
much about IA64.
