My change is x86 only, but the tests are not. These tests were added on your suggestion that the coverage for masked `nbits` was lacking, which is not related to the change I was making. And the test file explicitly asks to keep the tests in sync between x86 and aarch64. Do you see any benefit in splitting it further?

Is it not? I don't understand then how this works. Phabricator states that D155622 <https://reviews.llvm.org/D155622> was added as a parent, doesn't that make this (test) commit its child?
