trace: add workaround for SystemTap PR13296

SystemTap sdt.h sometimes results in compiled probes without sufficient
information to extract arguments.  This can be solved in a slightly
hacky way by encouraging the compiler to place arguments into registers.

This patch fixes the apic_reset_irq_delivered() trace event on Fedora 20
with gcc-4.8.2-7.fc20 and systemtap-sdt-devel-2.4-2.fc20 on x86_64.
