x86: Rename VF_AVX512VL_VF1_128_256 to VF1_AVX512ER_128_256
Since ix86_emit_swsqrtsf shouldn't be called with DF vector modes, rename
VF_AVX512VL_VF1_128_256 to VF1_AVX512ER_128_256 and drop DF vector modes.

* config/i386/sse.md (VF_AVX512VL_VF1_128_256): Renamed to ...
(VF1_AVX512ER_128_256): This. Drop DF vector modes.
(rsqrt<mode>2): Replace VF_AVX512VL_VF1_128_256 with
VF1_AVX512ER_128_256.
