[llvm] Don't preserve analysis results after EmbedBitcodePass (#146118)

Expensive checks complains when we mark them as preserved. The bitcode
being embedded generally doesn't change anything important in the
module, but some things are modified under ThinLTO, like vtables under
WPD. This became a non-issue when we cloned the module, but after we had
to revert that in #145987, we need to handle this case properly.
