This patch doesn't really change anything yet. I simply dumped the order in which we
were sorting the opcodes, disabled the automatic sorting and added some validation,
then changed BytecodeList.rb so the source matches the previous order.

In a subsequent patch I'll actually use a different order based on the Metadata
alignment requirements so we can get rid of all padding in the MetadataTable.

* Source/JavaScriptCore/bytecode/BytecodeList.rb:
* Source/JavaScriptCore/generator/DSL.rb:
