Add a default parameter to String.prototype.repeat

[NEG40]

• Suggested new syntax: String.prototype.repeat(count, default)
• Somewhere in the code: if (count < 0 && default >= 0) count = default;

Currently String.prototype.repeat(count) only allows a count >= 0, adding a default would allow count to be negative without causing a RangeError. The default argument should be optional and the function should throw a RangeError when count < 0 and default is undefined, this will allow the update to not potentially affect other code.

Only place I could find that may be the source for this function is node/deps/v8/src/builtins/string-repeat.tq which I started dabbling in implementing this change here but I dont really know how to test this.

Node.js does not control this. This comes from the JavaScript language and is implemented in V8.
