Gui Andrade b0ffa8befe [MSAN] Pass Origin by parameter to __msan_warning functions 
Summary:
Normally, the Origin is passed over TLS, which seems like it introduces unnecessary overhead. It's in the (extremely) cold path though, so the only overhead is in code size.

But with eager-checks, calls to __msan_warning functions are extremely common, so this becomes a useful optimization.

This can save ~5% code size.
