Hi guys,

This is a proposal we remove /msvclto option which is a minor lld-only
option from lld-link. That option was added as a hack to invoke MSVC
link.exe from lld-link so that it let link.exe do LTO and generate PDB. I
think we don't need that hack anymore because our LTO and PDB generation is

I don't think there's a real use of the option, but if you have any
concern, let me know. I'll remove the option if no one cares about it.
