IRGen: Enable update of extended frame pointer entry on x86_64

[aschwaighofer]

So far this was only enabled on arm64. Let's see whether the x86_64 backend can handle it.

Assertion failed: (CurrentState.load(std::memory_order_relaxed).Flags.getStatus() == Status::Idle && "actor not idle during destruction?"), function destroy, file /Users/buildnode/jenkins/workspace/swift-PR-macos/branch-main/swift/stdlib/public/Concurrency/Actor.cpp, line 430.

On i386, looks unrelated. This patch should only change IRGen on x86_64.
