0cfea5b7 - [BitcodeReader] Avoid quadratic complexity in intrinsic upgrade (#150032)

[BitcodeReader] Avoid quadratic complexity in intrinsic upgrade (#150032) When materializing a function, we'd upgrade all calls to all upgraded intrinsics. However, this would operate on all calls to the intrinsic (including previously materialized ones), which leads to quadratic complexity. Instead, only upgrade the calls that are in the materialized function. This fixes a compile-time regression introduced by #149310.
