    ### How to reproduce:

```llvm
define zeroext i32 @test_f32_to_u32(float %a) nounwind {
entry:
  %conv = fptoui float %a to i32
  ret i32 %conv
}
```

```sh
llc --mtriple loongarch64 --mattr=+f,+d -o - f32-to-u32.ll
```

### Expected result:

| f32 | u32      |
|------------|----------|
| -1         | 0        |
| -2 | 0        |
| 4294967296 | ffffffff |
| NAN        | 0        |
| +INFINITY  | ffffffff |
| -INFINITY  | 0        |

### Unexpected result:

| f32        | u32(Clang) | u32(GCC) |
|------------|------------|----------|
| -1         | ffffffff   | ffffffff |
| -2         | fffffffe   | fffffffe |
| 4294967296 | 0 | ffffffff |
| NAN        | 0          | 0        |
| +INFINITY  | ffffffff | ffffffff |
| -INFINITY  | 0          | 80000000 |
