Create a rethrow function to properly handle non-recoverable Throwables

[runningcode]

Related to #5513, we want to create a function/lambda so that we can catch Throwable and safely rethrow errors that we shouldn't catch.

The types of exceptions and errors that should be rethrown should be OOMs, ProcessDeath, Stackoverflow, InterruptedException and other types of errors (research this).

Example

fun rethrowFatal(t: Throwable) {
  if (t is X) {
     throw t
  } else if (t is Y) {
     throw t
  }
  // just ignore or log?
}

so it can be used like:

try {
  doDangerousThing()
} catch(t: Throwable) {
  rethrowFatal(t)
}

Ideally we shouldn't use this function often, just when we really don't want to crash.
