Emit vmov.i64 to load 0.0 into FP reg when neon enabled.
* config/arm/arm.md: (arch): Add neon.
(arch_enabled): Return yes for arch neon when TARGET_NEON.
* config/arm/vfp.md (movdf_vfp): Add w/G as alternative 3. Add
neon_move as type for alt 3. Add arch attr enabling alt 3 for neon.
Emit vmov.i64 for alt 3. Renumber alternatives 3 to 8. Adjust
attributes for alt renumbering. Mark alt 3 as non-predicable.
(thumb2_movdf_vfp): Likewise.
