4bfea803ed [SVE] Remove checks for warnings in scalable-vector tests.
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.

1652ed61e6 [SVE][CodeGen] Add README for SVE-related warnings in tests
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.

4ab4d5df20 [SVE] Add checks for no warnings in SVE tests
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.

This reverts commit fb495c31701b2cd697cf4282f63764c9cefd49c0.

Was causing test failures and broke buildbot.

650025e84c [AArch64][SVE] Add intrnisics for saturating scalar arithmetic
Summary:
The following intrnisics are added:
  * @llvm.aarch64.sve.sqdec{b|h|w|d|p}
  * @llvm.aarch64.sve.sqinc{b|h|w|d|p}
  * @llvm.aarch64.sve.uqdec{b|h|w|d|p}
  * @llvm.aarch64.sve.uqinc{b|h|w|d|p}

For every intrnisic there a scalar variants (with n32 or n64 suffix) and
vector variants (no suffix).
