Because the "pure" var-tracking hash table slots are also exceeded and
are therefore disabled by the compiler, too. So disabling all of
var-tracking saves another few seconds.
But if you guys are somehow fond of compile time hogs in the test suite,
I would recommend using "--param max-vartrack-size=0" on this test
case...
