Zi is a confusing name for this variable since it's checking `-g`. It'd probably be better to call it `HasDebug` or something to that effect. This also means our diagnostics (which match dxc) being specific about `/Zi` are a bit misleading, since `clang-dxc` also accepts `-g`, but that's probably not a big deal.
