Enable more sanitizers in make develop (#1588)

- `-fsanitize=undefined` encompasses multiple checks we were specifying

- "detect_leaks=1" for `__asan_default_options` checks for memory leaks
  (except for with macOS clang++, which does not support LSan)

- `-fsanitize=float-divide-by-zero` is an extra UBSan check
  (and reveals a UB bug to fix with fixed-point `DIV` and `LOG`)
