relative to the normal stack alignment of the target (e.g., when using
ebp as framepointer, all addresses are offset 8 to the stack pointer) in
the temp generator. This enables allocating temps/locals with the correct
alignment as long as the required alignment is not bigger than the
guaranteed stack pointer alignment (fixes mantis #15582 on systems where
the stack pointer is at least aligned to 16 bytes; e.g., not yet on
i386-platforms other than darwin)
