[X86] AVX512: Generate Pat<>'s for the vpermt2* intrinsics via multiclass
This new multiclass, avx512_perm_table_3src derives from the current one and
provides the Pat<>. The next patch will add another Pat<> that uses the
writemask.
Note that I dropped the type annotation from the intrinsic call, i.e.: (v16f32
VR512:$src1) -> R512:$src1. I think that this should be fine (at least many
intrinsic calls don't provide them) and it greatly reduces the number of
template arguments.
