  [llvm][SVE] IR intrinsics for quadword permutation instructions.

Summary:
Adding intrinsics and codegen patterns for:

* trn1 <Zd>.q, <Zm>.q, <Zn>.q
* trn2 <Zd>.q, <Zm>.q, <Zn>.q
* zip1 <Zd>.q, <Zm>.q, <Zn>.q
* zip2 <Zd>.q, <Zm>.q, <Zn>.q
* uzp1 <Zd>.q, <Zm>.q, <Zn>.q
* uzp2 <Zd>.q, <Zm>.q, <Zn>.q

These instructions are defined in Armv8.6-A.
