This PR splits up the SCC that the compiler manages into (potentially)
multiple ones after
performing lambda lifting. This aids both the closed term extractor and
the elimDeadBranches pass as
they are both negatively influenced when more declarations than required
are within one SCC.
This PR adds more selectors for TCP and Signals.
It also fixes a problem with `Selectors` that they cannot be closures
over a promise, otherwise it causes the waiter promise to never be
dropped.
This PR aims to fix the Timer API selector to make it finish as soon as
possible when unregistered. This change makes the `Selectable.one`
function drop the `selectables` array as soon as possible, so when
combined with finalizers that have some effects like the TCP socket
finalizer, it runs it as soon as possible.
This PR implements a basic async framework as well as asynchronously
running timers using libuv.
