Fraser Cormack	f3e9047249	[VP] Add vector-predicated reduction intrinsics ... This patch adds vector-predicated ("VP") reduction intrinsics corresponding to each of the existing unpredicated `llvm.vector.reduce.*` versions. Unlike the unpredicated reductions, all VP reductions have a start value. This start value is returned when the no vector element is active. Support for expansion on targets without native vector-predication support is included. This patch is based on the ["reduction slice"](https://reviews.llvm.org/D57504#1732277) of the LLVM-VP reference patch (https://reviews.llvm.org/D57504).

Simon Moll	74d45b884c	[VP] Binary floating-point intrinsics. ... This patch implements vector-predicated intrinsics on IR level for fadd, fsub, fmul, fdiv and frem. There operate in the default floating-point environment. We will use constrained fp operand bundles for constrained vector-predicated fp math (D93455).

Simon Moll	733b319948	[VP,Integer,#1] Vector-predicated integer intrinsics ... Summary: This patch adds IR intrinsics for vector-predicated integer arithmetic. It is subpatch #1 of the [integer slice](https://reviews.llvm.org/D57504#1732277) of [LLVM-VP](https://reviews.llvm.org/D57504). LLVM-VP is a larger effort to bring native vector predication to LLVM.
