Undo "Don't include an object header for instructions in the text section."

This undoes most of b2f3e8efe1f32bacad99ddbedbc434a6102d8be2.

This optimization prevents precompiled code from being disabled and re-enabled, because disabling causes the code to lose its only reference to its own instructions. This was okay for precompilated code that ran without a JIT because it is never disabled, but precompiled code that runs in a JIT will become disabled when corresponding optimized code is compiled and re-abled after a deopt.
