[IA64] align signal-frame even when not using alternate signal-stack
At the moment, attempting to invoke a signal-handler on the normal
stack is guaranteed to fail if the stack-pointer happens not to be
16-byte aligned. This is because the signal-trampoline will attempt
to store fp-regs with stf.spill instructions, which will trap for
misaligned addresses. This isn't terribly useful behavior. It's
better to just always align the signal frame to the next lower 16-byte
boundary.
