Remove dependancy on having the Instruction buffer in order to
deref Structures used for property access and global resolves.
Instead, we put references to the necessary Structures in axillary
data structures on the CodeBlock. This is not an ideal solution,
as we still pay for having the Structures in two places and we
would like to eventually just hold on to offsets into the machine
code buffer.
- Also removes CodeBlock bloat in non-JIT by #ifdefing the JIT
only data structures.
