cmd/internal/obj: use string instead of LSym in Pcln
In a concurrent backend, Ctxt.Lookup will need some form of concurrency protection, which will make it more expensive. This CL changes the pcln table builder to track filenames as strings rather than LSyms. Those strings are then converted into LSyms at the last moment, for writing the object file. This CL removes over 85% of the calls to Ctxt.Lookup in a run of make.bash. Passes toolstash-check.
