[IA64] fix stack alignment for ia32 signal handlers
This fixes the setup of the alignment of the signal frame, so that all
signal handlers are run with a properly aligned stack frame.
The current code "over-aligns" the stack pointer so that the stack frame
is effectively always mis-aligned by 4 bytes. But what we really want
is that on function entry ((sp + 4) & 15) == 0, which matches what would
happen if the stack were aligned before a "call" instruction.
i386 and x86_64 are already fixed by d347f372273c2b3d86a66e2e1c94c790c208e166
