Memory leak due to trace recorder value capturing

[Fidget-Spinner]

Bug report

Bug description:

Currently we Py_XDECREF((PyObject *)(uintptr_t)buffer[pc].operand0); only at the last part of uop_optimize, but we don't handle any of the error cases. This means if the JIT errors, it's possible to leak memory.
