2d Arm Neon sdot op, and lowering to the intrinsic.
This adds Sdot2d op, which is similar to the usual Neon intrinsic except that it takes 2d vector operands, reflecting the structure of the arithmetic that it's performing: 4 separate 4-dimensional dot products, whence the vector<4x4xi8> shape. This also adds a new pass, arm-neon-2d-to-intr, lowering this new 2d op to the 1d intrinsic. Reviewed By: nicolasvasilache Differential Revision: https://reviews.llvm.org/D102504
