Fix ALIGN_DOWN() macro on 64bit.
When the align parameter was a 32bit value (like all default integer literals),
and the to-be-aligned value is a pointer the upper 32bit got corrupted because
the value was casted down to 32bit.
Note: This hasnt been a problem because apparently the sim always gets 32bit
addresses (I found this when compiling Rockbox as a library).
