Test verifies https://github.com/FirebirdSQL/firebird/commit/137c3a96e51b8bc34cb74732687067e96c971226
(Postfix for #6583: enable support of int128 in bin_* family of functions).
FBTEST: functional.datatypes.int128_binary_operations
NOTES:
[20.06.2023] pzotov
Evaluation of bin_shr(-2^127, 127) should give result of -1. Before 5.0.0.1082 it was wrong: +1.
Checked on 5.0.0.1082.
Fix for FB 4.x will be soon (message from Alex, 20.06.2023 08:42).
