Summary:
Initial NUMA support:
- associate CPU with domain
- associate memory ranges with domain
- identify domain for devices
- limit device interrupt binding to appropriate domain
- Additionally fixes a bug in the setting of Maxmem which led to
only memory attached to the first socket being enabled for DMA
A pmap variant can opt in to numa support by by calling `numa_mem_regions`
at the end of pmap_bootstrap - registering the corresponding ranges with the
VM.
This yields a ~20% improvement in build times of llvm on dual socket POWER9
over non-NUMA.
Original patch by mmacy.
