David Sherwood f96f4eb390 [SVE] Add more warnings checks to clang and LLVM SVE tests 
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.
