Annotate no_return and returns_twice functions.
When building the bionic tests, we use -fno-builtins, which turns off
clang's recognition of vfork as a magical function that can return
twice. Explicitly annotate our returns_twice functions to ensure that
we generate correct code even in -fno-builtins (and while we're at it,
annotate the no_return functions as well, so we generate faster code).
