SI-9076 SAM in REPL gives non-termination of Java 8 Stream

@DarkDimius said:

As far as I understand the reason, I've fixed in in dotty by making lambdas inside static modules be non static and refer to module itself through this. scala/scala3@3b0cb48

We could also fix this by changing the encoding in the REPL to be like the currently experimental class-based encoding. This has a workaround as well, so not a release blocker.

There are a lot of tickets in this area. Besides, scala/bug#9076, there's scala/bug#8119 and scala/bug#9824.

(I personally am not sure, without going back over it, how many "different" issues there actually are here.)

the best minimal reproducer I know that is 2.12-specific is:

for (i <- (1 to 100).par) yield i

this hangs the 2.12 REPL but not the 2.11 REPL
