giles 2af31248f2 js-on-sx: js-num-to-int guards NaN/Infinity → 0 (+2 String)

Spec ToUint16 (String.fromCharCode argument coercion) maps non-finite
values to 0. We had bare (floor v) which left inf/-inf/nan through,
breaking:
  String.fromCharCode(Infinity).charCodeAt(0) === 0      // was "" → err
  String.fromCharCode(NaN).charCodeAt(0) === 0           // was "" → err

Add NaN/inf/-inf guards returning 0 before the floor+signed-flip path.

Unit 521/522, slice 148/148 unchanged.
String 38/100 → 40/100 (+2: fromCharCode/S9.7_A1, S9.7_A2.1).
