Adjust ix86_rtx_costs for pternlog_operand_p.
r15-1100-gec985bc97a0157 improves handling of ternlog instructions,
now GCC can recognize lots of pternlog_operand with different
variants.
The patch adjust rtx_costs for that, so pass_combine can
reasonably generate more optimal vpternlog instructions.
.i.e
for avx512f-vpternlog-3.c, with the patch, 2 vpternlog are combined into one.

gcc/ChangeLog:
* config/i386/i386.cc (ix86_rtx_costs): Adjust rtx_cost for
pternlog_operand under AVX512, also adjust VEC_DUPLICATE
according since vec_dup:mem can't be that cheap.
gcc/testsuite/ChangeLog:
* gcc.target/i386/avx2-pr98461.c: Scan either notl or
vpternlog.
* gcc.target/i386/avx512f-pr96891-3.c: Also scan for inversed
condition.
* gcc.target/i386/avx512f-vpternlogd-3.c: Adjust vpternlog
number to 673.
* gcc.target/i386/avx512f-vpternlogd-4.c: Ditto.
* gcc.target/i386/avx512f-vpternlogd-5.c: Ditto.
* gcc.target/i386/sse2-v1ti-vne.c: Add -mno-avx512f.
