Subject: [PATCH] QmlCompiler: Do not re-resolve iterator value types
We've resolved the value type in the type propagator. Trying to do it
again in the code generator, after the iterator may have been adjusted,
is quite wrong. If we resolve the list value type on a type that's not
a list (anymore), then we get an invalid type, which subsequently
crashes.
Amends commit a173d50a9e54d2a21a5207f6c66bb54bb8f3a612.
Pick-to: 6.8
