Before this commit sirit generated a stream of tokens that would then be inserted to the final SPIR-V binary. This design was carried from the initial design of manually inserting opcodes into the code. Now that all instructions but labels are inserted when their respective function is called, the old design can be dropped in favor of generating a valid stream of SPIR-V opcodes. The API for variables is broken, but adopting the new one is trivial. Instead of calling OpVariable and then adding a global or local variable, OpVariable was removed and global or local variables are generated when they are called. Avoiding duplicates is now done with an std::unordered_set instead of using a linear search jumping through vtables.
