LGTM.com - false positive for C++ missing return statement

**Description of the false positive**

Hi, there! I'm trying to add a fatal logging level to the logging infra. `LOG(FATAL)` will abort hence won't return. The macro is a wrapper around a stream-like class, whose destructor will call `abort()`, so after printing out the fatal error message, the program will be ternminated (refer to [this](https://github.com/iovisor/bpftrace/pull/1449/commits/89e940313767b4bcd475d535a788f1f1f825e39a) for more context). The destructor is marked with C++ attribute `[[noreturn]]`, which will make the compiler happy. I've also tried to suppress the alert with `// lgtm[cpp/missing-return]` but it won't work (remind me if I have done it in the wrong way). My guess is "missing return" is taken as an error so it won't be suppressed. But I'd think that since C++ provides the `[[noreturn]]` attribute to reassure the compiler, it should be considered an accepted behavior. Any thoughts on this?
