Subject: fix: disable scope reuse & associated dchecks
This change was introduced in https://crrev.com/c/5630974 which reuses
scope info objects across allocations. Unfortunately, this change seems
to be not yet fully cooked and causes crashes with normal usage of V8.
In particular, Node.js call's V8's `v8::ScriptCompiler::CompileFunction`
method. This ends up wrapping the source code in a function, which this
code is not yet prepared to handle. The generated function wrapper
(created by V8) has no source position, so it reports being at the start
of the source, which may overlap with other scopes that are in the
original source. This new feature adds a "UniqueIdInScript" concept that
is derived from the source position of a scope, along with the invariant
that inner scopes have a higher ID than outer scopes, which does not
hold for the above situation.
This patch is not intended to remain indefinitely. Once the upstream
feature stabilizes, we can remove this patch. Unfortunately, there is no
public tracking bug for this feature nor the crashes its been causing,
so we'll have to keep an eye on this for the time being.
