Revert of Reland of Remove slots that point to unboxed doubles from the StoreBuffer/SlotsBuffer. (patchset #3 id:40001 of https://codereview.chromium.org/988363002/)

Reason for revert:
Increased rate of Chrome crashes. Requires further investigation.

Original issue's description:
> Reland of Remove slots that point to unboxed doubles from the StoreBuffer/SlotsBuffer.
>
> The problem is that tagged slot could become a double slot after migrating of an object to another map with "shifted" fields (for example as a result of generalizing immutable data property to a data field).
> This CL also adds useful machinery that helps triggering incremental write barriers.

Remembering the current branch is a relic from the past
where no work-dir checkout was used. Now this doesn't give
much benefit and screws up the script if it was left in
a bad state (e.g. after a master restart).

Error.stack contains function.name if its type is string.
Otherwise if function have inferred name then .stack contains it.
For functions from eval .stack property contains "eval".

Since incremental marking hasn't completed yet at this point, we can't
use the MC's root visitor.

Also, we shouldn't hurry with incremental marking while

This fixes some failures on MIPS. Though not all of them, since
MIPS does not correctly implement set_target_internal_reference.

Platform ports that use this RelocInfo kind need to implement
set_target_internal_reference accordingly to distinguish between
INTERNAL_REFERENCE and INTERNAL_REFERENCE_ENCODED.
