Accept null $location in SoapClient::__setLocation()
Currently an empty string is used to unset the location. Once
again, it makes more sense to use a null value for this purpose
(though the special behavior of empty strings is retained).
The code comment above the function also explicitly indicates
that null should be accepted, and the function does return null
rather than an empty string for the old location value (if it
is missing).

Make SoapVar arguments nullable
$typeName, $typeNamespace, $nodeName and $nodeNamespace all
special-case the empty string and don't set the property entirely
in that case. It makes more sense to use null to indicate absence
here (though of course the empty string behavior is retained).

Optimize ZEND_COUNT opcodes on arrays in the jit
Avoid the overhead of a call and checking types
when the argument is definitely an array.
Avoid the overhead of gc when `__destruct` won't get called.
This seemed cheap enough to check for in the jit.
Because of https://wiki.php.net/rfc/restrict_globals_usage
we can be sure in the ZEND_COUNT handler that the array count does not have to
be recomputed in php 8.1.
The below example took 0.854 seconds before the optimization,
and 0.564 seconds after the optimization, giving the same result
```asm
mov 0x70(%r14), %rdi - Copy the count from the `zend_array*` pointer
mov %rdi, (%rax) - Store the count in the destination's value
mov $0x4, 0x8(%rax) - Store IS_LONG(4) in the destination's type
```

Added Inheritance Cache.
This is a new transparent technology that eliminates overhead of PHP class inheritance.
PHP classes are compiled and cached (by opcahce) separately, however their "linking" was done at run-time - on each request. The process of "linking" may involve a number of compatibility checks and borrowing methods/properties/constants form parent and traits. This takes significant time, but the result is the same on each request.
Inheritance Cache performs "linking" for unique set of all the depending classes (parent, interfaces, traits, property types, method types involved into compatibility checks) once and stores result in opcache shared memory. As a part of the this patch, I removed limitations for immutable classes (unresolved constants, typed properties and covariant type checks). So now all classes stored in opcache are "immutable". They may be lazily loaded into process memory, if necessary, but this usually occurs just once (on first linking).
The patch shows 8% improvement on Symphony "Hello World" app.

Make imagegd $file parameter nullable
It is explicitly documented to be nullable, and this matches other
functions like imagepng. It is also documented to accept a stream,
which it currently does not...

Make Phar $fileNotFoundScript nullable
While "" is already treated the same way as absence, null is the
logically correct default here. Making this one argument non-nullable
is particularly pecular when considering that the preceding $alias
and $index arguments are both nullable.

Make createDocument() $namespace nullable
According to the DOM specification, this argument should be
nullable. It's also supposed to be a required argument, but
not changing that at this point.
Fix #80706: mail(): Headers after Bcc headers may be ignored
We need to handle the case where a CRLF after a Bcc header is not the
beginning of a folding marker, because in that case the Bcc header was
not the last "thing".
Fix #74779: x() and y() truncating floats to integers
We must not use the locale dependent `atof()`, but instead use the
(hopefully) locale independent `zend_strtod()`, when converting string
representations of floating point numbers which are sent by the server.

Fix CLI server worker support
If we create separate listening sockets in each worker using
SO_REUSEADDR, then an incoming connection may be load-balanced
to a process that is already busy, either due to a long-running
request, or because it is a recursive request (in which case we
would deadlock).
Instead, only create one listening socket, and only create worker
forks afterwards. This way the incoming request will be served
by one of the workers that is currently listening for an incoming
connection.
When Phars are flushed, a new temporary file is created for each entry
which should be compressed, and the `compressed_filesize` is retrieved.
Afterwards, the Phar manifest is written, and only after that the files
are copied to the actual Phar. So for each such entry there is an open
temp file, what easily exceeds the limit.
Therefore, we use a single temporary file for all entries, and store
the start offset in the otherwise unused `header_offset` member. We
ensure that the `cfp` members are properly set to NULL even if flushing
fails, to avoid use after free scenarios.
This solution is based on a suggestion by @lserni[1].

Fix persistent leak on load_wsdl_ex failure
Move the load_wsdl_ex call into the zend_try that destroys the
docs hash table. The wsdl will be inserted into docs early on,
and will thus be released on subsequent bailout.
We remove the arbitrary restriction to `INT_MAX`; it is superfluous on
32bit systems where `ZEND_LONG_MAX == INT_MAX` anyway, and not useful
on 64bit systems, where larger files should be readable, if the
`memory_limit` is large enough.
