2021-08-17	[VP] Add vector-predicated reduction intrinsics	Fraser Cormack
	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).

2021-05-19	[VP] make getFunctionalOpcode return an Optional	Simon Moll
	The operation of some VP intrinsics do/will not map to regular instruction opcodes. Returning 'None' seems more intuitive here than 'Instruction::Call'. Reviewed By: frasercrmck Differential Revision: https://reviews.llvm.org/D102778
2021-05-04	Recommit "[VP,Integer,#2] ExpandVectorPredication pass"	Simon Moll
	This reverts the revert 02c5ba8679873e878ae7a76fb26808a47940275b Fix: Pass was registered as DUMMY_FUNCTION_PASS causing the newpm-pass functions to be doubly defined. Triggered in -DLLVM_ENABLE_MODULE=1 builds. Original commit: This patch implements expansion of llvm.vp.* intrinsics (https://llvm.org/docs/LangRef.html#vector-predication-intrinsics). VP expansion is required for targets that do not implement VP code generation. Since expansion is controllable with TTI, targets can switch on the VP intrinsics they do support in their backend offering a smooth transition strategy for VP code generation (VE, RISC-V V, ARM SVE, AVX512, ..).
