Bumping the max TypedArray length caused the typer to make different
representation decisions, which caused inefficient back-and-forth
conversions. This patch repairs the microbenchmark where this was
most significant.
There might be additional future work to ensure that TypedArray
accesses that actually use huge indices remain on the fast path as well.
