Swift: Disable stack protector pass

[jketema]

Although we do not have any Linux testing enabled, this works around crashes we were seeing on Linux with Swift.

Pull request overview

Disables Swift SIL stack protection in the extractor to work around Linux crashes during extraction.

Changes:

• Turns off swift::SILOptions::EnableStackProtection in the extractor’s SIL options setup.

Comments suppressed due to low confidence (1)

swift/extractor/main.cpp:84

• turnOffSilVerifications now also disables stack protection, which is not a verification toggle. Consider moving this setting to a more appropriately named helper (or renaming this function) so future changes don’t accidentally couple unrelated compiler options.

  options.VerifyAll = false;
  options.VerifyExclusivity = false;
  options.VerifyNone = true;
  options.VerifySILOwnership = false;
  options.EnableStackProtection = false;  // Causes crashes on Linux
