No need to wait for initialization on for this anymore.
Ever since Init was refactored to do basically no work, this hasn't been
necessary.
CPUID does need to still be initialized after HostFeatures though, so
need to ensure correct member ordering there.
This is blocking performance improvements. This backend is almost
unilaterally unused except for when I'm testing if games run on Radeon
video drivers.
Hopefully AmpereOne and Orin/Grace can fulfill this role when they
launch next year.
Hades and the vcruntime hits this very hard in memmove.

This performance is terrible because Cortex's LRCPC performance is bottom-tier.
Work around the performance issue by forcing things to do larger moves with vector moves instead.
It is not an external component, and it makes paths needlessly long.
Ryan seemed amenable to this when we discussed on IRC earlier.
