This reverts commit 4d5b878b61.
Reason for revert: Suspected to cause a failure on ChromeOS, which is blocking the roll - https://chromium-review.googlesource.com/c/chromium/src/+/2636263
Original change's description:
> [super] Store home object in Context instead of JSFunction
>
> This saves memory (the home object doesn't need to be stored for each
> method, but only once per class) and hopefully makes the home object
> a constant in the optimized code.
>
> Detailed documentation of the changes:
> https://docs.google.com/document/d/1ZVXcoQdf9IdMsnRI9iyUjyq9NDoEyx9nA3XqMgwflMs/edit?usp=sharing
