Some enchanced for loops are not enhanced.

Start at NetHandlerPlayClient.func_191980_a in the decompiler output shown in the issue and compare the REMOVE and INIT iterator loops with the existing enhanced loops. Trace the corresponding decompiler handling for these loops, then verify that eligible iterator-based loops are emitted consistently without changing the method's behavior.
