Add future for #26376, compiler hang during resolve

[cassella]

The same program compiles when a distinct array is created instead of passing a slice:

  var newnums = for i in 0..#nums.size-1 do nums[i+1];
  tryit(newnums);

@vasslitvinov ?

Since it's hanging in the resolve phase and all I can think it's resolving is the function, I dropped it in test/functions/resolution.

I picked a timeout of 25 aiming for a compilation timeout of 100 seconds. My laptop usually compiles hello world kinds of programs in under a minute, so I'm guessing 100 seconds is long enough for anywhere that needs to run tests.
