Functions with no body are assumed to potentially throw.
This PR is blocked by https://github.com/github/codeql-c-team/issues/2423, we first must address the unexplained loop IR inconsistency as this will increase those inconsistencies.
The prior PR 128053e adds an apparent inconsistency with respect to this PR by specifying explicit non-throwing functions. For SEH some of what have been marked as non-throwing actually do throw (e.g., memcpy may throw with respect to SEH). We will work on a separate PR to differentiate for SEH, but the prior PR doesn't involve IR so the inconsistency, to my understanding, wouldn't be noticed as this PR affects IR flow specifically.
