* config/i386/sse.md (VI248_AVX2, VI248_AVX512BW, VI248_AVX512BW_2):
New mode iterators.
(<shift_insn><mode>3<mask_name>): Change the last of the 3
define_insns for logical vector shifts to use VI248_AVX512BW
iterator instead of VI48_AVX512, remove <mask_mode512bit_condition>
condition, useless isa and prefix attributes. Change the first
2 of these define_insns to ...
(<mask_codefor><shift_insn><mode>3<mask_name>): ... this, new
define_insn for avx512vl.
(<shift_insn><mode>3): ... and this, new define_insn without
masking for non-avx512vl.
