Fix GH-16393: Assertion failure in ext/opcache/jit/zend_jit.c:2897

Fix JIT support for static properties of self and parent

Use original op_array when JIT compiling a Closure

zend_jit() assumes that Closure op_arrays have no scope, but this is not true
when using the hot counters, first exec, or trace triggers as they use the
executed op_array, which is in case of Closures is a copy, with a scope.

In the tracing JIT this problem is avoided as we fetch the original op_array
when compiling a Closure. Here I replicate this for the hot counters and first
exec triggers.

Fixes GH-16186
Closes GH-16200

* Special case zend_interrupt_function in JIT code

* refactor to use ZEND_VM_SET_OPCODE_NO_INTERRUPT

* Split atomic exchange into load + store

It is difficult to determine performance of atomics sometimes. In this
case, the separate load+store is still correct, and a load does not
cause a modification, and might be faster for some platforms than an
exchange. A load+store is slower than an exchange, but we're fine
trading the penalty to the slow path and keeping the happy path faster.

Fix GH-13834: Applying non-zero offset 36 to null pointer in zend_jit.c (#13846)

* Fix GH-13834: Applying non-zero offset 36 to null pointer in zend_jit.c

ssa_op can be NULL in function JIT. Doing pointer arithmetic on a NULL
pointer is undefined behaviour. Undefined behaviour can be dangerous
because the optimizer may assume then that the variable is not actually
NULL.

To solve this:
1. Add ADVANCE_SSA_OP() to safely add an offset to ssa_op in zend_jit.c
2. For inference, add an extra offset argument to the helper functions.

To reproduce this, use Clang (not GCC) on a test like
sapi/cli/tests/gh12363.phpt (or other tests also work).

* Remove -fno-sanitize=pointer-overflow flag from CI

* Fix NULL pointer offsets added to the stack_map

* Fix an offset add on a potentially NULL ssa->ops

* Fix NULL pointer arithmetic in zend_range_info()

* Address review comments
