Make it a little harder to slip in use-after-free bugs by nulling out
references to the parser object after handing it off to freeParser().

It's safe to call BaseObject::object() from your destructor _unless_
the handle is weak; then it's the weak callback that is calling your
destructor and the object will have been released by the time the
destructor runs.

Weak handles put strain on the garbage collector and the parser handle
doesn't need to be weak in the first place. This change should improve
GC times on busy servers a little.

The REPL global object lazy loads modules by placing getters for each.
This causes MakeDomainCallback() to be run if a native module is loaded
from the REPL, but if the domain module hasn't been loaded then there
are no enter/exit callbacks to be called. Causing an assert() to fail.
Fix the issue by conditionally running the callback instead of asserting
it is available. Also add "addon" test to verify the fix.

PR #8034 came with a test to make sure that timers expiry is based on
monotonic time and not on wall-clock time. However, a bug in the
implementation broke timers with non-integer delays. A fix for this
issue was provided with PR #8073, but it didn't come with a test.
Because #8073 fixed a subtle issue that could reappear in the future,
and because the impact of such an issue would be significant, I suggest
adding this test.
The test would timeout after 1 minute if the issue was reproduced.
Otherwise it will run very quickly.

Allow to create an executable with no external dynamic libraries, also the
ones from the system. This is somewhat dependent of the used C lib, for
example glibc has some internal dynamic libraries loaded by itself, but for
other ones like eglibc or dietlib, this would produce a true static linked
executable. This can be of interest for embebers or resource constraints
platforms, but the main reason for this is to allow to use a Javascript
file as Linux kernel 'init' on NodeOS.

Currently, cluster workers can be removed from the workers list in three
different places:
- In the exit event handler for the worker process.
- In the disconnect event handler of the worker process.
- In the disconnect event handler of the cluster master.
However, handles for a given worker are cleaned up only in one of these
places: in the cluster master's disconnect event handler.
Because these events happen asynchronously, it is possible that the
workers list is empty before we even clean up one handle. This makes
the assert that makes sure that no handle is left when the workers
list is empty fail.
This commit removes the worker from the cluster.workers list only when
the worker is dead _and_ disconnected, at which point we're sure that
its associated handles are cleaned up.
Fixes#8191 and #8192.

There is no need to split the host by hand in `url.js` – Punycode.js
takes care of it anyway. This not only simplifies the code, but also
adds support for RFC 3490 separators (i.e. not just U+002E, but U+3002,
U+FF0E, and U+FF61 as well).

Documentation states that `querystring.unescape` may be overridden to
replace unescaper during parsing. However, the function was only
being used as a fallback for when the native decoder throws (on a
malformed URL). This patch moves the call to the native function and
the try/catch around it into querystring.unescape then has the parser
always invoke it, so that an override will always be used.

fd80a31e06 has introduced a segfault
during redundant boundary check elimination (#8208).
The problem consists of two parts:
1. Abscense of instruction iterator in
`EliminateRedundantBoundsChecks`. It was present in recent v8, but
wasn't considered important at the time of backport. However, since
the function is changing instructions order in block, it is
important to not rely at `i->next()` at the end of the loop.
2. Too strict ASSERT in `MoveIndexIfNecessary`. It is essentially a
backport of a45c96ab from v8's upstream. See
https://github.com/v8/v8/commit/a45c96ab for details.
