This matches the existing behavior of treating CTRL_C_EVENT, CTRL_BREAK_EVENT as a synthesized SIGINT event.
See https://docs.microsoft.com/en-us/windows/console/handlerroutine for a good documentation source upstream to confirm these values.
As for the usage of these events, the "Timeouts" section of that upstream documentation is important to note, especially the limited window in which to do any cleanup before the program will be forcibly killed (defaults typically 5s, but as low as 500ms, and in many cases configurable system-wide).
These events are especially relevant for Windows containers, where these events (particularly `CTRL_SHUTDOWN_EVENT`) are one of the only ways containers can "gracefully" shut down (https://github.com/moby/moby/issues/25982#issuecomment-466804071).
This was verified by making a simple `main()` which implements the same code as in `ExampleNotify_allSignals` but in a `for` loop, building a `main.exe`, running that in a container, then doing `docker kill -sTERM` on said container. The program prints `Got signal: SIGTERM`, then exits after the aforementioned timeout, as expected. Behavior before this patch is that the program gets no notification (and thus no output) but still exits after the timeout.

This will improve liveness analysis slightly, the same logic as
isdirectiface curently does. In:
type T struct {
m map[int]int
}
v := T{}
v.m = make(map[int]int)
T is considered "fat", now it is not. So assigning to v.m is considered
to clobber the entire v.
This is follow up of CL 179057.
