1.0.5.35: stack alignment on x86/Darwin, once more
* Stack alignment cannot be changed after arguments have been pushed
on stack: ALLOCATE-NUMBER-STACK-SPACE is the place to do this, and
nowhere else.
* Use the RESET-STACK-POINTER logic on all x86 platforms for
simplicity.
* Factor out the alignment logic to ALIGN-STACK-POINTER.
* Clear DF unconditionally when calling out, which means that Solaris
doesn't need to switch it back and forth. (Darwin, Solaris, and Win32
all need DF cleared for call-out.)
