c11527fc68
Removes the following unused code from the compiler: * The ICU expander appears to be some really old code converting ICUs into legacy-style control flow directives. It's annoying to keep this one since we need to update it any time the AST changes. * The `PipeCollector` class wasn't used anywhere. * The `partitionArray` function wasn't used anywhere. * The `newArray` function was used only in one test and it can be easily replaced with `new Array().fill`. PR Close #61668
