fix: pass descriptor to _GUARD_BINARY_OP_EXTEND_{LHS,RHS} in tier2 optimizer

The descriptor pointer was not being passed as an operand when adding
_GUARD_BINARY_OP_EXTEND_LHS and _GUARD_BINARY_OP_EXTEND_RHS operations
in the tier2 optimizer. This caused the executor to read garbage/NULL
values from the inline cache, leading to assertion failures and crashes
in JIT-compiled code.

Fixed by passing the descriptor as a uintptr_t operand, following the
same pattern used for other pointer-valued operations like
_CALL_METHOD_DESCRIPTOR_*.

Fixes CI failures where multiple test platforms were failing.
