I have added a new file:
llvm/test/CodeGen/AArch64/README
that describes what to do in the event one of the SVE codegen tests
fails the warnings check. In addition, I've added comments to all
the relevant SVE tests pointing users at the README file.

There are now quite a few SVE tests in LLVM and Clang that do not
emit warnings related to invalid use of EVT::getVectorNumElements()
and VectorType::getNumElements(). For these tests I have added
additional checks that there are no warnings in order to prevent
any future regressions.

Summary:
This patch implements custom floating-point reduction ISD nodes that
have vector results, which are used to lower the following intrinsics:
* llvm.aarch64.sve.fadda
* llvm.aarch64.sve.faddv
* llvm.aarch64.sve.fmaxv
* llvm.aarch64.sve.fmaxnmv
* llvm.aarch64.sve.fminv
* llvm.aarch64.sve.fminnmv
SVE reduction instructions keep their result within a vector register,
with all other bits set to zero.
Changes in this patch were implemented by Paul Walker and Sander de
Smalen.
