Introduce a new PartialAlias response for AliasAnalysis. For most
...
AliasAnalysis consumers, PartialAlias will be treated as MayAlias.
For AliasAnalysis chaining, MayAlias says "procede to the next analysis".
PartialAlias will be used to indicate that the query should terminate,
even though it didn't reach MustAlias or NoAlias.

Reserved registers are filtered from the allocation order, and any valid hint is

Formalize the notion that AVX and SSE are non-overlapping extensions from the compiler's point of view.

Passing -mattr=-avx,+sse42 should serve to restore legacy SSE support when desirable.
