[SVE] Upgrade VectorType tests to test new types

I think you can just write *RHS (operator<< is overloaded for const Type &T)

152

Do you not want to test for getElementCount here?

I chose not to because both types are instances of ScalableVectorType, and by definition that means that EC.Scalable is true. But then again, I suppose the purpose of tests is to ensure that stays true. I'll make the change.

LGTM!

Right, I misread this as getNumElements. In that case both are indeed fine though.

In my mind, the most important thing is that is has a different name to prevent copy/paste and template duck typing issues. however, if after having seen it in the wild, you think it's too similar to getNumElements(), I'm open to changing it.

This seems to cause the following warning on GreenDragon (
http://green.lab.llvm.org/green/job/clang-stage1-cmake-RA-expensive/15985/console)

It would be great if you could take a look.

/Users/buildslave/jenkins/workspace/clang-stage1-cmake-RA-expensive/llvm-project/llvm/unittests/IR/VectorTypesTest.cpp:231:39: warning: suggest braces around initialization of subobject [-Wmissing-braces]

Those warnings pop up all over the place (including other places in that build) if you use clang 5.0 or older to build clang. clang prints a warning because std::array is actually a struct that contains a C array. Newer versions suppress the warning, though.

Maybe we should teach CMake to pass -Wno-missing-braces to older versions of clang.
