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.

In general SVE intrinsics are considered predicated and merging
with everything else having suitable decoration. For predicated
zeroing operations (like the predicate logical instructions) we
use the "_z" suffix. After this change all intrinsics use their
expected names (i.e. orr instead of or and eor instead of xor).
I've removed intrinsics and patterns for condition code setting
instructions as that data is not returned as part of the intrinsic.
The expectation is to ask for a cc flag explicitly.
For example:
a = and_z(pg, p1, p2)
cc = ptest_<flag>(pg, a)
With the code generator expected to use "s" variants of instructions
when available.
