I have one too, even bootstrapped/regtested overnight, just didn't get to
writing new testcases that would cover the cases that need testing (i.e. that
-f{,no-}sanitize-recover=float-divide-by-zero rather than
-f{,no-}sanitize-recover=integer-divide-by-zero decides on *_abort for float
division and the behavior for -fsanitize=undefined
-fno-sanitize-recover=integer-divide-by-zero or -fsanitize=undefined
-fno-sanitize-recover=signed-integer-overflow (i.e. when integer-divide-by-zero
and signed-integer-overflow differ in the recover method).
