Fix Thumb2 load / store addressing mode matching code. Do not use so_reg form to
...
match base only address, i.e. [r] since Thumb2 requires a offset register field.
For those, use [r + imm12] where the immediate is zero.
Note the generated assembly code does not look any different after the patch.
But the bug would have broken the JIT (if there is Thumb2 support) and it can
break later passes which expect the address mode to be well-formed.

Use vAny type to get rid of Neon intrinsics that differed only in whether
