[ARM] Begin adding IR intrinsics for MVE instructions.
This commit, together with the next few, will add a representative sample of the kind of IR intrinsics that we'll need in order to implement the user-facing ACLE intrinsics for MVE. Supporting all of them will take more work; the intention of this initial series of commits is to implement an intrinsic or two from lots of different categories, as examples and proofs of concept. This initial commit introduces a small number of IR intrinsics for instructions simple enough that they can use Tablegen ISel patterns: the predicated versions of the VADD and VSUB instructions (both integer and FP), VMIN and VMAX, and the float->half VCVT instruction (predicated and unpredicated). When using VPT-predicated instructions in automatic code generation, it will be convenient to specify the predicate value as a vector of the appropriate number of i1. To make it easy to specify all sizes of an instruction in one go and give each one the matching predicate vector type, I've added a system of Tablegen informational records describing MVE's vector types: each one gives the underlying LLVM IR ValueType (which may not be the same if the MVE vector is of explicitly signed or unsigned integers) and an appropriate vNi1 to use as the predicate vector. (Also, those info records include the usual encoding for the types, so that as we add associations between each instruction encoding and one of the new `MVEVectorVTInfo` records, we can remove some of the existing template parameters and replace them with references to the vector type info's fields.) The user-facing ACLE intrinsics will receive a predicate mask as a 16-bit integer, so I've also provided a pair of intrinsics i2v and v2i, to convert between an integer and a vector of i1 by just changing the register class.
