* Adds a currently unused x86-64 assembler as a prerequisite for possible future JIT compilation * Fix a bug in table iteration (closes Possible table iteration bug #504) * Improved warning method when function is used as a type * Fix a bug with unsandboxed iteration with pairs() * Type of coroutine.status() is now a union of value types * Bytecode output for tests/debugging now has labels * Improvements to loop unrolling cost estimation * Report errors when the key obviously doesn't exist in the table
