No particularly noteworthy changes, as most complex API changes were already supported in SM45 and done. The addition of JSStructuredCloneData allows to remove our custom class. Changes: - InformalValueTypeName is back in the API, so remove our implementation. - Stop using JSRuntime entirely in favour of JSContext* - JSPropertyDescriptor is renamed. - CompartmentOptions are tweaked slightly (no functional changes) - JS::Construct - API update. - JSClass split - API update. - A js.msg error message was removed, so we had to use a different one. - Tests fix: fix comparison of union instances - Disable warning in spidermonkey Vector.h - Update error reporting to SM52 (minor API updates) - Ignore warnings about unused return values (would come from OOM, which isn't recoverable) Most of the patching was done by Itms. Tested by: Stan, Freagarach Fixes #4893 Differential Revision: https://code.wildfiregames.com/D3095 This was SVN commit r24203.
