regress-336820 is testing that joining a very sparse array to create a too-big string results in a RangeError, rather than a crash. Reducing the largest index by two orders of magnitude speeds this up (on x64 debug) by 8x (from 8 seconds down to 1). Given that this test takes nearly 9 minutes on arm64 sim debug, I hope to see big ones there too.
