Prefix all global functions calls with \ to skip the look up and resolve process and go straight to the global function

For the record: except for a limited list of special functions, adding a leading \ to function calls provides no measurable benefit. There is zero performance improvement from these. Since this worsen readibility, I'm on the side this is undesired. (just saying; my opinion has no importance here :) )

@nicolas-grekas In the long term I'd prefer to go with use function abc; over \abc(); for readability. Thank you for that list I was unaware of that. There are some situations where we did gain a significant performance gain from doing this so I'll investigate that.

P.S. As far as I'm concerned everyone's opinion is considered and kept in mind. But we can't guarantee we agree or act on them.
