Subject: [PATCH 1/2] Triple::normalize: Use none as OS for XX-none-ABI
When we parse 3-components triples, if the Arch and Env have been
parsed successfully, we have to make a choice between Vendor and
OS for the unrecoginzed component. Noramlly it is the middle one.
In the current code, Vendor is choosed, and then OS is fallbacked
to unknown. It is OK for most cases. But if the unrecoginzed
component is `none`, it is expected to be OS instead of Vendor.
Fixes: #89582.
