Calvin Rose 486f980579 First draft flow typing analysis and OVM stub. 
In order to further optimize bytecode, we need
to do some static analysis to annotate the assembly with
types. First (untested) draft of this idea that works by scanning
the bytecode instructions in order, keeping track of bitsets of possible
types for each active slot. We also record all possible types that go
through the inputs and come out of the outputs of each instruction.

When we hit a conditional branch, we save one side of the branch to a
stack to continue later, using a hash map of states to avoid infinite
stack growth. We then continue with the other side of the branch as
normal.

When we are finished with the current exectution trace, pop a state from
the stack and start over. We repeat this until the stack is empty.
(Still need some short-circuit conditions to prevent searching
 incredibly large state space - for example, just add one more maximally
 vague trace after a limit of N iterations).

Once the stack is empty, we have should have annotations on the possible
input and output types of each instruction, as well as other information
such as can the instruction possibly error, did it ever continue to
the next instruction, or did this instruction ever execute at all.

Untested, almost certainly full of bugs big and small.
