[ARM] Enable auto-vectorization for copysignf
gcc/
* config/arm/arm.c (NEON_COPYSIGNF): New enum.
(arm_init_neon_builtins): Support NEON_COPYSIGNF.
(arm_builtin_vectorized_function): Likewise.
* config/arm/arm_neon_builtins.def: New macro for copysignf.
* config/arm/neon.md (neon_copysignf<mode>): New pattern for vector
copysignf.
gcc/testsuite/
* gcc.target/arm/vect-copysignf.c: New testcase.
