After D98856 these tests will by default break (fatal_error) if any of
the wrong interfaces are used, so there's no longer a need to have a
RUN line that checks for a warning message emitted by the compiler.
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 more 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:
The following intrinsics are added:
* @llvm.aarch64.sve.ldff1.gather
* @llvm.aarch64.sve.ldff1.gather.index
* @llvm.aarch64.sve.ldff1.gather_sxtw
* @llvm.aarch64.sve.ldff1.gather.uxtw
* @llvm.aarch64.sve.ldff1.gather_sxtw.index
* @llvm.aarch64.sve.ldff1.gather.uxtw.index
* @llvm.aarch64.sve.ldff1.gather.scalar.offset
Although this patch is quite substantial, the vast majority of the
implementation is just a 'copy & paste' of the implementation of regular
gather loads, including tests. There's only a handful of new
definitions:
* AArch64ISD nodes defined in AArch64ISelLowering.h (e.g. GLDFF1)
* Seleciton DAG Types in AArch64SVEInstrInfo.td (e.g.
AArch64ldff1_gather)
* intrinsics in IntrinsicsAArch64.td (e.g. aarch64_sve_ldff1_gather)
* Pseudo instructions in SVEInstrFormats.td to workaround the issue of
use-before-def for the FFR register.
