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:
Creates the SVEIntrinsicOpts pass. In this patch, the pass tries
to remove unnecessary reinterpret intrinsics which convert to
and from svbool_t (llvm.aarch64.sve.convert.[to|from].svbool)
For example, the reinterprets below are redundant:
%1 = call <vscale x 16 x i1> @llvm.aarch64.sve.convert.to.svbool.nxv4i1(<vscale x 4 x i1> %a)
%2 = call <vscale x 4 x i1> @llvm.aarch64.sve.convert.from.svbool.nxv4i1(<vscale x 16 x i1> %1)
The pass also looks for ptest intrinsics and phi instructions where
the operands are being needlessly converted to and from svbool_t.
