bug 1671887 will add a mechanism to mark ParserAtoms that will be used while instantiation.
we can reuse the mechanism to eagerly instantiate ParserAtoms at the beginning of CompilationInfo::instantiateStencils.
This has the following merits:
- code/memory locality
- ParserAtoms to JSAtom conversion in later steps become infallible

Make the preparation step added by bug 1671887 required, and use the marked flag
to figure out which atom should be instantiated.
At the beginning of instantiation, instantiate all unresolved atoms,
and use the result in the later steps.
