[issue28727] Implement comparison (x==y and x!=y) for _sre.SRE_Pattern

[Serhiy Storchaka]

Serhiy Storchaka added the comment:

There is a problem with locale-depending flags. The same pattern may be compiled with the LOCALE flag to different pattern objects in different locales. Perhaps we should compare the compiled code instead of pattern strings. Or both.
