Summary:
The undef and the infinite loop at the end cause this test to be translated
unpredictably. In particular, the checked-for `mpy` disappears under
certain legal optimizations (e.g. the one in D50222).
Since the use of these constructs is not relevant to the behavior tested,
according to the header comment, this change, suggested by @kparzysz,
eliminates them.
Was initially committed in r341046, but was reverted.

Summary:
As suggested in D50222, this has been refactored into a separate patch.
The undef and the infinite loop at the end cause this test to be translated
unpredictably. In particular, the checked-for `mpy` disappears under
certain legal optimizations (e.g. the one in D50222).
Since the use of these constructs is not relevant to the behavior tested,
according to the header comment, this change, suggested by @kparzysz,
