- rebase across jlebar's r261774 => implicit_inputs gone, ForceSuccessCommand is new
- .h file is found relative to include paths => introduce -find-pch-source= cc1 flag to handle that
- turns out several important things (`#pragma comment(lib...)`) aren't serialized yet => put this behind -internal-enable-pch for now so we can improve on this feature in-tree (and once it's ready that flag will go away again)
- address view comments
