concatAppendOne should allocate using the indexing type of the array if it cannot merge https://bugs.webkit.org/show_bug.cgi?id=160261 <rdar://problem/27530122> Reviewed by Mark Lam. Before, if we could not merge the indexing types for copying, we would allocate the the array as ArrayWithUndecided. Instead, we should allocate an array with the original array's indexing type. * runtime/ArrayPrototype.cpp: (JSC::concatAppendOne): * tests/stress/concat-append-one-with-sparse-array.js: Added.
