Javed Absar 3d92d7ab36 [ARM] Fix Neon vector type alignment to 64-bit 
The maximum alignment for ARM NEON data types should be 64-bits as specified
in ARM procedure call standard document Sec. A.2 Notes.
This patch fixes it from its current larger natural default values, except
for Android (so as not to break existing ABI).
