[llvm] llvm-reduce: Use 80 dashes for section separator in status printing (PR #133686)

[Matt Arsenault via llvm-commits]

Previously it printed a shorter sequence of dashes, which were shorter
than most of the printed pass descriptions. It is much shorter than
the printed names after fea6b388055284f37852e615fbf5b40a3ba34249.
Make this look more consistent by filling a standard terminal width.
