[PATCH 7/9] jscript: Compare numbers in a Map bitwise for equality.

[Gabriel Ivăncescu]

Native treats -0 and 0 differently, so it must be doing a bitwise
comparison. This might not order the numbers correctly, but that's not
important, since we don't need them sorted other than for quick lookup
(and any arbitrary sorting is fine, as long as it's consistent).

[PATCH 8/9] jscript: Implement Set on top of Map.

[Marvin]

Hi,

While running your changed tests, I think I found new failures.
Being a bot and all I'm not very good at pattern recognition, so I might be
wrong, but could you please double-check?

Full results can be found at:
https://testbot.winehq.org/JobDetails.pl?Key=112582

Your paranoid android.

[PATCH 9/9] jscript: Use proper error description for invalid Set 'this'.

[Gabriel Ivăncescu]

Map and Set share the same error code, but the description given is different,
so we need to throw it manually.
