Description:
------------
The spec is not correct/complete for certain bitwise operations in conjunction with strings. Consider the following:
http://3v4l.org/fR1pE

For instance, the spec does not mention anything about the ~ in conjunction with strings:
https://github.com/php/php-langspec/blob/master/spec/10-expressions.md#unary-arithmetic-operators

The section about bitwise operator mentions that the return type would be int and that the operands would be converted to integers, which is both wrong for strings:
https://github.com/php/php-langspec/blob/master/spec/10-expressions.md#bitwise-inclusive-or-operator

etc.
