Raymond Hettinger 0e413bd288 Issue 18719: Remove a false optimization
Remove an unused early-out test from the critical path for
dict and set lookups.

When the strings already have matching lengths and hashes,
there is no additional information gained by checking the first
characters (the probability of a mismatch is already known to
be less than 1 in 2**64).

Ronald Oussoren 3687e8055c Issue #18427: str.replace could crash the interpreter with huge strings.
This fixes two places where 'int'  was used to represent
the size of strings, instead of 'Py_ssize_t'.

(The issue is not present in the corresponding code in the 3.x branches)

Fixes #18427
