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:
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

Without any positive bias, there is nothing for the spill placer to to. It will
spill everywhere.

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.

c41ab789a0 RuntimeDyld should use the memory manager API. 
Start teaching the runtime Dyld interface to use the memory manager API
for allocating space. Rather than mapping directly into the MachO object,
we extract the payload for each object and copy it into a dedicated buffer
allocated via the memory manager. For now, just do Segment64, so this works
on x86_64, but not yet on ARM.
