Previous episode was at 987a3460 (KT-45915).
Apparently, it's not enough to run psi2ir for all modules, and then
backend for all modules. If there are several modules in the chunk, IR
in any one of them can reference IR of any other one after psi2ir.
So we would end up in a situation where we're running codegen for the
first module, but the second module is completely unlowered. This would
break some assumptions in the codegen, for example in KT-49575, codegen
would see a reference to a top-level function from another module, and
would fail because the function has no containing class (since file
facades have not been generated yet!), and thus must be an intrinsic,
yet no such intrinsic is known to the codegen.
The solution is to run lowerings first on all modules, and then run
codegen on all modules. The kind of error explained above shouldn't be
possible anymore, because lowerings have to deal both with lowered and
unlowered code from other files all the time, so lowerings can't assume
that reference from other module is lowered either (or unlowered).
The code is not very nice, but hopefully it can be improved as soon as
we get rid of the old JVM backend (and maybe later with the migration to
FIR too).
