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 func

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
