not "ArrayLiteralSpread". Previously --filter Array/ would match nothing.

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.

All the bytecode handlers were added a one test, so we would get a
total on all of the bytecode handler benchmarks. It is not a good
indicator when we total unrelated benchmarks. So added more categories
to group only related benchmarks together. This also makes it easier
to look at the results.

Functions that take mandatory parameters plus a number of optional
parameters, that need to be materialized as an Array are quite common.
The simplest possible case of this is essentially:
function foo(mandatory, ...args) { return args; }
Babel translates this to something like:
function foo(mandatory) {
"use strict";
for (var _len = arguments.length,
args = Array(_len > 1 ? _len - 1 : 0),
_key = 1; _key < _len; _key++) {
args[_key - 1] = arguments[_key];
}
return args;
}
The key to great performance here is to make sure that we don't
materialize the (unmapped) arguments object in this case, plus that we
have some kind of fast-path for the Array constructor and the
initialization loop.
This microbenchmark ensures that we have decent performance even in the
case where the assignment to args is polymorphic, i.e. the arguments
have seen different elements kinds, starting with FAST_HOLEY_ELEMENTS
and then FAST_HOLEY_SMI_ELEMENTS.
