[PATCH] D24693: [CodeGen] Don't emit lifetime intrinsics for some local variables

[Vitaly Buka via cfe-commits]

vitalybuka added a comment.

Intrinsics are invalid there, code is generated in such way that variable is being accessed after lifetime.end.
I suspect that optimizer can make invalid code because of this, but I can't reproduce.
So I think it's safer to remove them at all and don't wait for miscompile reports.

Still if performance is greater concern than potential miscompiles, I can limit this only to asan-use-after-scope.
