George Peter Banyard b40ae80804 Convert iterable into an internal alias for Traversable|array (#7309) 
This does a compile time transformation of ``iterable`` into ``Traversable|array`` which simplifies some of the LSP variance handling.

The arginfo generation script from stubs is updated to produce a union type when it encounters the type ``iterable``
Extension functions which do not regenerate the arginfo, or write them manually are still supported by mimicking the compile time transformation while registering the function.

Type Reflection is preserved for single ``iterable`` (and ``?iterable``) to produce a ReflectionNamedType with name ``iterable``, however usage of ``iterable`` in union types will be converted to ``array|Traversable``

Levi Morrison 280fd680c8 Make vm_interrupt and timed_out atomic (#8327) 
This is done by adding a new zend_atomic_bool type. The type
definition is only available for compiler alignment and size info; it
should be treated as opaque and only the zend_atomic_bool_* family of
functions should be used.

Note that directly using atomic_bool is complicated. All C++ compilers
stdlibs that I checked typedef atomic_bool to std::atomic<bool>, which
can't be used in an extern "C" section, and there's at least one usage
of this in core, and probably more outside of it.

So, instead use platform specific functions, preferring compiler
intrinsics.

Chen, Hu c1fcd45eeb JIT: Add IBT support (#8636) 
Indirect Branch Tracking (IBT) is part of Intel's Control-Flow
Enforcement Technology (CET). IBT is hardware based, forward edge
Control-Flow-Integrity mechanism where any indirect CALL/JMP must target
an ENDBR instruction or suffer #CP.

This commit adds IBT support for JIT:
1. Add endbr32/64 instruction in Dynasm.
2. Insert endbr32/64 in indirect branch target for jitted code.

gcc support CET since v8.1 and set it to default since gcc 11. With this
commit, endbr is inserted in jitted code if PHP is compiled with "gcc
-fcf-protection=full/branch".

Arnaud Le Blanc 69d263e2a1 Add JIT guards for INIT_METHOD_CALL when the method may be modified (#8600) 
Non-polymorphic methods can be modified from one request to an other due to recompilation or conditional declaration.

Fixes GH-8591

Christoph M. Becker 06c3f9b043 Use proper cast 
Casting to `void**` silences the compiler, but only works because that
is dereferenced to a generic `void*`.

Dmitry Stogov 6c25413183 Add JIT guards for INIT_FCALL instructions and functions that may be modified 
For methods we reuse mechanism of polymorphic calls.
For regular function we invalidate the whole root trace.

We need to export `__MUSL__` so that phpize builds can see the proper
macro, and also need to fix "_tsrm_ls_cache" usage for musl.

Closes GH-8180.
