AAPCS64 requires 16 byte stack alignment. Set the bits in the system
control register to enable alignment fault exceptions if the stack
pointer is not correctly aligned when used as a base address in load or
store instructions.
drahn@ pointed out that FreeBSD made this change in svn rev 295270 and
believes we should do the same.
