Make the auto-pusher recover easier.

The auto-push script is only used in an automated fashion
on bots. It doesn't need to check for a clean git
environment as it has a special workdir checkout.

If the release creation fails for whatever reason (e.g.
a master restart happens in the middle), the workdir
checkout might be left dirty. Any new attempt of the auto
pusher then bails out.

After this change it will call the create_release script
in any case which tidies up the workspace on startup.

Proxies up the chain are guaranteed to provide access if we had access to the receiver, since otherwise we wouldn't have been able to compile the stub in the first place. If the security check would change, the window navigates, changing the map of the JSGlobalProxy.

[strong] Declaration-after-use errors.

We cannot yet detect use-before-declaration in general, because for that we'd
need to analyze the context when compiling. But we can detect an error case
where we first see a use, then a declaration.

For this, I also added end position tracking (needed for error messages) to
VariableProxy.

Note: the position naming is completely inconsistent: start_position &
end_position, position & end_position, pos & end_pos, beg_pos & end_pos, to name
a few. This doesn't fix all of it, but tries to unify towards start_position &

Do not touch a binary op IC target in code object marked for lazy deopt.

Bad scenario:

- Enter a binop IC miss handler from optimized code object C from call
  site S,

- From the binop IC, invoke arbitrary javascript that lazy deopts C,
  so all relocation info is nuked and replaced with lazy deopt entries'
  reloc info. In particular, there is no reloc info for S.

- Still from the arbitrary JavaScript, make IC target's code object move.
  Note that the call site S is not updated.

- Return to the miss handler and inspect the IC's target. This will try
  to get the target from S, but that is a potentially invalid pointer.

It is quite possible that we will have to do a similar fix for other ICs,
but we will have to find a reliable repro first. I am not submitting a
repro here because it is quite long running and brittle (it
relies on code compaction happening while in the binop IC).
