Vector variants of the new C23 powr routines. These provide same maximum error error as pow by virtue of relying on shared approximation techniques and sources. Note: Benchmark inputs for powr(f) are identical to pow(f). Performance gain over pow on V1 with GCC@15: - SVE powr: 10-12% on subnormal x, 12-13% on x < 0. - SVE powrf: 15% on all x < 0. - AdvSIMD powr: for x < 0, 40% if x subnormal, 60% otherwise. - AdvSIMD powrf: 4% on x subnormals or x < 0.
