    Original change's description:
    > [ic] Add a new MegaDOM IC
    >
    > This patch implements the MegaDOM IC setup and access. A new MegaDOM
    > IC state indicates that we've seen only DOM accessors at this access
    > site.
    >
    > This CL only adds support for DOM getters in LoadIC, other kinds of
    > access will be added in follow on CLs.
    >
    > Still remaining TODO before shipping:
    > 1. Have a mechanism to invalidate the protector
    > 2. Have a mechanism to find the accessors that aren't overloaded
    > 3. Use a new builtin to miss to runtime on access check failure
