The scalar instruction of this is `llvm.trunc`. However the naming of
ISD::VP_TRUNC is already taken by `trunc` of the LLVM IR. Naming this as
`vp.ftrunc` would likely cause confusion with `vp.fptrunc`. So adding
`vp.roundtozero` that will look similar to `vp.roundeven`.

This adds LLVMAnyPointerToElt to use instead of LLVMPointerToElt.
This allows us to preserve the address space as part of the type

llvm.vp.merge interprets the %evl operand differently than the other vp

Usage and naming of macros in VPIntrinsics.def has been inconsistent. Rename all property macros to VP_PROPERTY_<name>. Use BEGIN/END scope macros to attach properties to vp intrinsics and SDNodes (instead of specifying either directly with the property macro).

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
