Fix DecideToPretenureDuringCompilation to work with --no-lazy-feedback

DecideToPretenureDuringCompilation expects a particular number of
allocation sites. So enable lazy feedback allocation always in the test.
It is possible to make the test work for --no-lazy-feedback-allocation
too, but the test already runs in a controlled environment by setting
various flags so it is OK to enable lazy feeedback allocation to keep
test simple
