Revert unintended part of the commit (the key==dummy test wasn't supposed to change).

Remove unneeded dummy test from the set search loop (when the hashes match we know the key is not a dummy).

Issue #23269 : Tighten search_loop in set_insert_clean()
...
Instead of masking and shifting every loopup, move the wrap-around
test outside of the inner-loop.

Set the hash values of dummy entries to -1. Improves quality of entry->hash == hash tests.

A hybrid of and-masking and a conditional-set-to-zero produce even faster search loop.

Clean-up, simplify, and slightly speed-up bounds logic in set_pop().
...
Elsewhere in the setobject.c code we do a bitwise-and with the mask
instead of using a conditional to reset to zero on wrap-around.
Using that same technique here use gives cleaner, faster, and more
consistent code.

...
* Move the test for an exact key match to after a hash match
* Use "used" as a loop counter instead of "fill"
* Minor improvements to variable names and code consistency
