3890e397c3 Add an OpReinterpret operation to TableGen's NeonEmitter. 
An OpReinterpret entry is handled by translating it to OpCast intrinsics for
all combinations of source and destination types with the same total size.
This will be used to generate all the vreinterpret intrinsics.

194aa58066 Support using macros for Neon intrinsics implemented without builtins. 
Intrinsics implemented with Clang builtins could already be implemented as
either inline functions or macros, but intrinsics implemented directly
(without builtins) could only be inline functions.

37a0b54fb5 Simplify code in Neon intrinsics. No functional changes intended. 
For most intrinsics, there is no need to allocate a temporary to hold the
result value; just return it directly.

377296e301 Assign arguments of Neon intrinsic macros to local temporaries. 
Since we're casting them for the calls to the builtins, we need this to
make sure their types get checked in the same way they would if the intrinsics
were implemented as inline functions.

181b76d503 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).

6904d7af1c 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.
