  Log Message:
  -----------
  Triple::normalize: Use none as OS for XX-none-ABI (#89638)

When parsing a 3-component triple, after we determine Arch and Env, if
the middle component is "none", treat it as OS instead of Vendor.

See:
https://discourse.llvm.org/t/rfc-baremetal-target-triple-normalization/78524
Fixes: #89582.
