Daniel J Blueman ad03a9c25d x86/numachip: Add Numachip IPI optimisations 
When sending IPIs, first check if the non-local part of the source and
destination APIC IDs match; if so, send via the local APIC for efficiency.

Secondly, since the AMD BIOS-kernel developer guide states IPI delivery
will occur invarient of prior deliver status, avoid polling the delivery
status bit for efficiency.
