Original commit message:

    Properly handle holes following spreads in array literals

    Before this change, the spread desugaring would naively call
    `%AppendElement($R, the_hole)` and in some cases $R would have
    a non-holey elements kind, putting the array into the bad state
    of exposing holes to author code.

    This patch avoids calling %AppendElement with a hole, instead
    simply incrementing $R.length when it sees a hole in the literal
    (this is safe because $R is known to be an Array). The existing
    logic for elements transitions takes care of giving the array a
    holey ElementsKind.

Full original message:

  Revert "repl: disable Ctrl+C support on win32 for now"

The original fix was a stop gap until a libuv update landed.
As the libuv update has not yet landed on v6.x the revert should
not have landed. This commit reverts 1d400ea reapplying the
stopgap fix until we update libuv.
