David Sherwood 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.
