Use name-discarding LLVM context

This is only applicable when neither of --emit=llvm-ir or --emit=llvm-bc are not
requested.

In case either of these outputs are wanted, but the benefits of such context are
desired as well, -Zfewer_names option provides the same functionality regardless
of the outputs requested.

Should be a viable fix for https://github.com/rust-lang/rust/issues/46449
