Bob Wilson 3e8f3f94ef Add explicit casts for vector arguments to Neon builtins. 
This avoids warnings with -Wvector-conversions.  Radar 8228022.

Bob Wilson 4e22a38759 Change the 'x' type modifier for Neon intrinsics to force a signed integer. 
This makes it symmetric with the 'u' modifier that forces an unsigned type.
This is needed for unsigned vector shifts, where the shift amount still needs
to be signed.  PR8482 (Radar 8603521).

Bob Wilson dfac58bed1 Tidy up some things in <arm_neon.h>. 
Stop defining types with "__neon_" prefixes and then using typedefs without
the prefix; there's no reason to do that anymore.  Remove types that combine
multiple Neon vectors and treat them as a single long vector; they are not
used.

Bob Wilson 02d6467291 Use float64 instead of int64 vector elements for NEON vget_low and vget_high 
functions, since int64 is not a legal type and using it leads to inefficient
code.  PR8036.
