Make the array elements in msunit/regress/regress-542823 larger, so that it takes fewer of them to force the joined string to go into large object space. Also, set the array's size dynamically based on the maximum non-large object size, rather than having a fixed magic "large enough" size, and verify that the resulting joined string is indeed in LO space. This reduces the runtime of this test under slow_path and gc-stress from minutes to seconds.
