  -----------
  [AArch64][SVE] Add SVE2 intrinsics for bit permutation & table lookup

Summary:
Implements the following intrinsics:
 - @llvm.aarch64.sve.bdep.x
 - @llvm.aarch64.sve.bext.x
 - @llvm.aarch64.sve.bgrp.x
 - @llvm.aarch64.sve.tbl2
 - @llvm.aarch64.sve.tbx

The SelectTableSVE2 function in this patch is used to select the TBL2
intrinsic & ensures that the vector registers allocated are consecutive.
