34625fdb5a [Builtins] Array.prototype.forEach perf regression on dictionaries.
An unnecessary call to ToString() on the array index caused trips to
the runtime. The fix also includes performance micro-benchmarks so
we'll have a harder time regressing this case in future.

fb922b1764 [TurboFan] Allow unreliable maps in array builtins
We don't currently inline array builtins if we detect any side effects
between the load of the receiver map and the call to the builtin.
The introduction of a map check allows us to be more permissive.

a0ab7d4527 [JSPerfTests] Refactoring in Array 2nd-order builtin tests
The (numbing) repetition in these tests were leading to errors when
writing new tests. Now a function DefineHigherOrderTests() can be
used to succinctly describe a test on (mostly) a single line.

c633282daf [builtins] Array.map should transition output arrays.
If the input array is small, then the cost of a trip to the
runtime to transition the ElementsKind is too expensive.

aa5852a294 Add JSPerf tests for more 2nd-order Array builtins
Every, Some, Reduce, ReduceRight. Added a test that should improve
when TurboFan inlines these builtins. Updated Map and Filter tests
to include a TurboFan inline test.
