[dev.typeparams] cmd/compile: cleanup unified IR file format a little

Browse source 
This CL makes two changes:

1. It moves object symbols and code tags into a new "relocName"
relocation, which should eventually allow getting rid of objStub.

2. It moves the type parameter data into the relocObjDict relocation,
so everything related to writing out dictionaries is contained there.
