  Log Message:
  -----------
  Crash on WebCore::FrameLoader::effectiveReferrerPolicy() after 274396 at main on ARM64 with GCC -O3
https://bugs.webkit.org/show_bug.cgi?id=273703

Reviewed by Michael Catanzaro.

This workarounds a bug on GCC (affecting at least GCC 12, 13, 14, 15-nightly)
where the compiler produces wrong code on ARM64 at certain optimization levels
(like -O3) which seems related to lambdas and variants.

This wrong code later leads to a crash when the browser starts at
WebCore::FrameLoader::effectiveReferrerPolicy()
