Subject: [PATCH] Remove a test that no longer makes sense.

It was testing a linear scan feature:

  Test if linearscan is unfavoring registers for allocation to allow
  more reuse of reloads from stack slots.

The greedy register allocator doesn't access any stack slots in this
function, so the linear scan feature was not being tested.
