[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.

Just minor comments.

Thank you.

You might want to remove this too?

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,
