Group reference types in binary format. (#4774)
Grouping all references together makes it easier for baseline compilers to
zero out memory (as the zeroing out may be different for MVP types vs.
references).
This puts all references together, either at the start or the end. As a
heuristic for that we see if the first local is a reference. As the optimizer
will sort locals by frequency, this ensures that the most-frequent local
stays in index 0.
Fixes #4773. See more details there
