[VFDatabase] Testsuite for scalar functions are vector functions with VF =1

[masoud.ataei]

Summary

Fixing test suite of the committed PR: https://reviews.llvm.org/D78054.
I am proposing to remove the PowerPC target triple in the test suite.

[fpetrogalli]

Just minor comments.

Thank you.

llvm/test/Transforms/LoopVectorize/vectorizeVFone.ll

26–27

You might want to remove this too?

27–28

Also, given that all references to ppc seems to be dropped, maybe rename __atand2_massv to vector_atan, so you can simplify the CHECK-NOT: to check for call fast <{{[0-9]+}} x double> @{{.*}}atan(.

Removing other dependencies to PowerPC machines in the test suits.

LGTM. Thanks for fixing.

[fpetrogalli]

Looks good to me too! Ship it! :)

Thank you,

Francesco
