e815dab69f Recompute hasPHIKill flags when shrinking live intervals.
PHI values may be deleted, causing the flags to be wrong. This fixes PR9616.

0e382192c1 PR9634: Don't unconditionally tell the AliasSetTracker that the PreheaderLoad
is equivalent to any other relevant value; it isn't true in general.
If it is equivalent, the LoopPromoter will tell the AST the equivalence.
Also, delete the PreheaderLoad if it is unused.

Chris, since you were the last one to make major changes here, can you check
that this is sane?

d8b4c4d74f A8.6.393
The ARM disassembler should reject invalid (type, align) encodings as invalid instructions.

So, instead of:

	vst2.32	{d0, d2}, [r3, :256], r3
