[ARM] 4630/1: Fix the vector stride of the double vector instruction.

The vector stride of the double-precision vector instructions must be changed
to 1-2 from even 2-4, because the double registers numbering has been
changed to 0-15 from even 0-30 by
1356c1948da967bc1d4c663762bfe21dfcec4b2f commit.
