Mark -march=native as expected-undocumented for the flag linter
--show-options emits the full token "-march=native", but compare-flags.py
strips documented flags at "=", so the ghc-flag directive reduces to
"-march" and never matches. List the full token here, consistent with
other value-variant flags such as -rtsopts=all and -fdiagnostics-color=always.
Issue reported in #27321.

Remove redundant Data.Bits import in CpuFeatures
testBit is already in scope via GHC.Prelude, which re-exports all of
Data.Bits. The explicit import tripped -Werror=unused-imports.
