TableGen: Add first class support for processor aliases

Previously isCPUStringValid was virtual so TableGen could emit an
AArch64 specific hack for recognizing cpu aliases. Teach tablegen
about aliases, and insert each alias into the CPU subtype table as its
own entry (sorted by name, carrying the canonical processor's features
and scheduling model).

There is further opportunity for code sharing improvements. AArch64's
aliases are consumed by ARMTargetDefEmitter to emit a custom inc file
in TargetParser which should be universalized.

AMDGPU: Use ProcessorAlias for legacy arch names

Older targets have aliasing names which were previously implemented
by defining a second copy of the processor, identical except for the name
Use the recently improved tablegen mechanism for defining name-only aliases.
This dedupliates some redundant table entries, like the sched model.
