[issue5057] Unicode-width dependent optimization leads to non-portable pyc file

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

issue5057-3.diff LGTM.

I added debug output in peepholer, ran tests and found that this optimization happened for unicode strings only in test_multibytecodec (where it used deliberately) and test_peepholer.  Seems as this is very rare case.
