When producing frontend arguments for sourcekitd, force the output mode to -typecheck so that we do not create any temporary output files in the driver. Previously, any sourcekitd operation that created a compiler invocation would create 0-sized .o file inside $TMPDIR that would never be cleaned up. The new swift-driver project handles temporaries much better as VirtualPath, and should not need this approach. rdar://62366123
