```
stage2: clean up preserving callee regs on the stack

Instead of using `push` and `pop` combo, we now re-use our stack
allocation mechanism which means we don't have to worry about
16-byte stack adjustments on macOS as it is handled automatically
for us. Another benefit is that we don't have to backpatch stack
offsets when pulling args from the stack.

```
