I tried that, but `parseSanitizeArgs` adds in the `SanitizerMask`,
`TrappingDefault`, so it enables these bits: `SanitizerKind::CFI |
SanitizerKind::LocalBounds` by default. This means more warnings are emitted
than what the user actually entered. I could work around this, but I thought my
approach would be cleaner. Let me know if you would prefer the
`parseSanitizeTrapArgs` approach though.
