Rollup merge of #125700 - Zalathar:limit-overflow, r=nnethercote
coverage: Avoid overflow when the MC/DC condition limit is exceeded Fix for the test failure seen in https://github.com/rust-lang/rust/pull/124571#issuecomment-2099620869. If we perform this subtraction first, it can sometimes overflow to -1 before the addition can bring its value back to 0. That behaviour seems to be benign, but it nevertheless causes test failures in compiler configurations that check for overflow. ``@rustbot`` label +A-code-coverage
