Finding and fixing performance regressions is a bit of a game of whack-a-mole. To get better visibility into potential performance regressions, we should have a code gen test suite. The issue is that code gen changes all the time so it's hard to test precisely. However, tests like this could flag probably issues:

@test filter(is_call, @code_llvm f(x)) == 0
@test filter(is_simd, @code_native f(x)) > 0
@test length(@code_native f(x)) ≤ 20

We have tests that do this, we could have more but they exist.
