sprintf() is now optimized by the compiler

[arokettu]

See: php/php-src#14546

Therefore is should be added to FunctionHelper::SPECIAL_FUNCTIONS

[bkdotcom]

has sprintf's function signature changed?
Is it now a language construct (like empty()) vs a function?

what makes it "special" ?

[arokettu]

@bkdotcom FunctionHelper::SPECIAL_FUNCTIONS is used by SlevomatCodingStandard.Namespaces.FullyQualifiedGlobalFunctions to indicate functions that can be optimized by compiler when fully qualified, at least that's what the code tells me

Implemented in dd05cd6
