  Log Message:
  -----------
  [DEBUGINFO] Propagate debug metadata for sext SDNode. (#135971)

In some cases of chained `sext` operators the debug metadata can be
missed. This patch propagates proper metadata to resulting node.

Particular case of issue is NVPTX codegen for function with bool local
variable:
```
void test(int i) {
  bool xyz = i == 0;
  foo(i);
}
```
