…710.4 (#595)

[dotnet/main-16.x] Update dependencies from dotnet/arcade

This was a custom change added in da3d772 but we missed porting that to recent branches.

Given we've not even noticed until now and it just causes building a bit more tools I'd argue it's better to just remove this.

The old flags were removed upstream: llvm#66850

It's ignored on other platforms and causes a warning in the log.

It breaks mono's AOT compiled code, because the specialized functions
are outside of generated EH frame code range.

We can re-enable it, once we fix EH frame generation for mono.
