David Sherwood 02650ac036 [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.

David Sherwood 3cfd74e64b [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.

Andrzej Warzynski be2b7ea89a [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).
