Log:
lld-link: For nonexisting inputs, omit follow-on diagnostics
For lld-link missing.obj, lld-link currently prints:
lld-link: error: could not open foo.obj: No such file or directory
lld-link: warning: /machine is not specified. x64 is assumed
lld-link: error: subsystem must be defined
The 2nd and 3rd diagnostics are consequences of the input not existing and are
not interesting. If input files are missing, the best thing we can do is point
that out and then return.
