Auto merge of #21646 - dotdash:default_target_cpu, r=Aatch
Using `generic` as the target cpu limits the generated code to the bare basics for the arch, while we can probably assume that we'll actually be running on somewhat modern hardware. This updates the default target CPUs for the x86 and x86_64 archs to match clang's behaviour. Refs #20777
