  -----------
  [mlir][Parser] Fix crash after block parsing failure (#128011)

Fix a crash when parsing malformed block that defines values that
preceding operations refer to (which would be a dominance error).

Previously: Producer multiple error messages and then crashes as
follows:
```
LLVM ERROR: operation destroyed but still has uses
```

Now: Report an error that the block is malformed. No crash.
