core: hal: With GCC14, some hal_intrin128.*_CPP_EMULATOR tests are failed.

### System Information

OpenCV version: 4.10.0-pre (4.9.0-531-g79af357cf4) 
Operating System / Platform: Ubuntu 24.04
Compiler & compiler version: GCC 14.0.1

### Detailed description

I faced strange test result with Ubuntu24.04 and GCC14 , 
I can't find the root cause at all, so I would like to share the problem with the OpenCV community.

I build OpenCV4(4.x) with GCC14 and run `./bin/opencv_test_core  --gtest_filter="*hal_intrin*CPP*" `.
Unexpectedly some test are failed.

```
[  FAILED  ] hal_intrin128.int32x4_CPP_EMULATOR
[  FAILED  ] hal_intrin128.uint32x4_CPP_EMULATOR
[  FAILED  ] hal_intrin128.uint64x2_CPP_EMULATOR
[  FAILED  ] hal_intrin128.int64x2_CPP_EMULATOR
[  FAILED  ] hal_intrin128.float32x4_CPP_EMULATOR
[  FAILED  ] hal_intrin128.float64x2_CPP_EMULATOR
```

But this result is very strange. It seems that both values are same, however google test determine they are not same.

[  FAILED  ] hal_intrin128.int32x4_CPP_EMULATOR (0 ms)
```

I investigated this problem, however I know only it may or may related with GCC optimization.
I have no more options to debug it. 

- I try to debug it with "debug build", however tests are passed successfully.
- I try to show data details with "std::hex" operator, however tests are passed successfully.

### Steps to reproduce

```bash
sudo apt install g++-14 gcc-14
cmake -S opencv4 -B build4-main_gcc14 -DCMAKE_CXX_COMPILER=g++-14 -DCMAKE_C_COMPILER=gcc-14 -GNinja
cmake --build build4-main_gcc14 
cd build4-main_gcc14 
./bin/opencv_test_core  --gtest_filter="*hal_intrin*CPP*"
```

### Issue submission checklist

- [X] I report the issue, it's not a question
- [X] I checked the problem with documentation, FAQ, open issues, forum.opencv.org, Stack Overflow, etc and have not found any solution
- [X] I updated to the latest OpenCV version and the issue is still there
- [X] There is reproducer code and related data files (videos, images, onnx, etc)
