fileset: insert hints where status should be computed
This will allow us to compute status against a narrowed set of files.
For example, "path:build/ & (unknown() + missing())" is rewritten as
"path:build/ & <withstatus>(unknown() + missing(), 'unknown missing')",
and the status call can be narrowed by the left-hand-side matcher,
"path:build/".
mctx.buildstatus() calls will be solely processed by getmatchwithstatus().
