What's Changed

• Fix size of userdata metatable array by @petrihakkinen in #1366
• Make os.clock use clock_gettime on FreeBSD by @Ketasaja in #1364
• Variety of bugfixes in the new solver
• Fix a bug in lua_resume where too many values might be removed from stack when resume throws an error

New Solver

• Fix an issue where we would hit a recursion limit when applying long chains of type refinements.
• Weaken the types of table.freeze and table.clone in the new solver so we can accept common code patterns like local a = table.freeze({x=5, x=0}) at the expense of accepting code like table.freeze(true).
• Don't warn when the # operator is used on a value of type never
