[clang-tidy] false negative for misc-const-correctness in function-try-block

[schenker]

The check misc-const-correctness of clang-tidy 19.0.0git (20d3815) does not work as expected for function-try-blocks.

For the following function the warning warning variable 'i' of type 'int' can be declared 'const' [misc-const-correctness] is generated.

int tp() {
  try {
    int i = 0;
    return i;
  } catch (...) {
    return 0;
  }
}

When the outer curly braces are ommited, the check does not report a warning.

int fn() try {
  int i = 0;
  return i;
} catch (...) {
  return 0;
}

This is because of "hasBody(compoundStmt", shouldn't be hard to fix, changing this into "hasBody(stmt" should do a trick.
