test/staging/sm/TypedArray/toLocaleString-detached.js assumes implementation-defined separator

[linusg]

From https://tc39.es/ecma262/#sec-%typedarray%.prototype.tolocalestring:

This is a distinct method that implements the same algorithm as Array.prototype.toLocaleString as defined in 23.1.3.32 except that TypedArrayLength is called in place of performing a [[Get]] of "length".

From https://tc39.es/ecma262/#sec-array.prototype.tolocalestring:

3. Let separator be the implementation-defined list-separator String value appropriate for the host environment's current locale (such as ", ").

This test assumes the implementation-defined separator is , without a space:

Line 40 in c125a8d

assert.sameValue(typedArray.toLocaleString(), "0,");

This is not true in at least Boa and Kiesel which both use , .
