This patch introduces the vector-predicated version of the
experimental_vector_splice intrinsic [1] at the IR level. It considers
the active vector length for both vectors and and uses a vector mask to
disable certain lanes in the result.

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).

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).
