[JSC] Use simple merge for TypedArray.prototype.sort
https://bugs.webkit.org/show_bug.cgi?id=314223
rdar://176291674
Reviewed by Keith Miller and Yusuke Suzuki.
Galloping merge trades code size for sorting performance. Absolute performance
isn't necessary for TypedArray sorting, so recoup some binary size by using a
simple merge for TypedArrays.
On a Release arm64 build, this PR reduces binary size by 955KB.
This is covered by existing sort tests.
