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:
Opcode=1641 Name=VST2b32_UPD Format=ARM_FORMAT_NLdSt(30)
 31 30 29 28 27 26 25 24 23 22 21 20 19 18 17 16 15 14 13 12 11 10  9  8  7  6  5  4  3  2  1  0

-------------------------------------------------------------------------------------------------

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

we now have:

4d81c9a6ba A8.6.92 MCR (Encoding A1): if coproc == '101x' then SEE "Advanced SIMD and VFP" 
Since these "Advanced SIMD and VFP" instructions have more specfic encoding bits
specified, if coproc == 10 or 11, we should reject the insn as invalid.

db529a8a5d Analyze blocks with uses separately from live-through blocks without uses. 
About 90% of the relevant blocks are live-through without uses, and the only
information required about them is their number. This saves memory and enables
later optimizations that need to look at only the use-blocks.
