benchmarks: add ng2_ftl and ng2_switch_ftl benchmarks (#11963) 

These benchmarks take the output of AoT
and manually tweaks it to explore possible
future changes to the compiler to produce
this output directly.

# Ng2 Faster Than BaseLine (FTL) Benchmark
This benchmark was produced in a similar way as `ng2_static_ftl`,
but starting from the `ng2` benchmark, i.e. the benchmark
that only uses 1 component that contains itself via 2 `NgIf`s.
1. Run AoT over the `TreeComponent` and `AppModule`
2. Move the `ComponentFactory` and the corresponding host view class
from `tree.ngfactory.ts` into `tree_host.ngfactory.ts`
3. Move the `NgModuleFactory` into the `app.ngfactory.ts`
4. Optimize the `tree.ngfactory.ts` (see below)
The goal of this benchmark is to explore what kind of
code the Ng2 compiler should generate in order to get faster.
I.e. right now, the Ng2 compiler _does not_ produce this kind of code,
but hopefully will in the future.
## Optimizations and cleanups
See `tree.ngfactory.ts` and `tree_leaf.ngfactory.ts`.
Performance:
- remove view factory functions, call the constructor of the view class directly
- remove `createInternal` and move the logic into the constructor
- generate direct calls to `detectChangesInternal` / `destroyInternal` of nested components
_and_ view containers, don't use `viewChildren` / `contentChildren`
- remove `Renderer` and `SanitizationService` to update
the dom directly via `document.createElement` / `element.appendChild` / setting
`Text.nodeValue` / `Element.style....`
- remove `AppElement` on component host elements
- custom implementation of `ViewContainerRef` that uses
the views as linked list, instead of an array (see `ftl_util`).
- custom implementation of TemplateRef which not use a closure, only a view and an index,
and the view has a factory method that switches over the index
(see `ftl_util`).
- Don't wrap Views into ViewRefs before passing to the user.
- View does not use an array to store root nodes,
but rather has a generated method `visitRootNodes` (see below)
- ViewContainer, TemplateRef and views have minimal amount of fields
- use `insertBefore` as primitive.
Code size:
- inputs for `NgIf`, `TreeComponent` are wrapped into view class / directive wrapper method
(see `ng_if.ngfactory.ts` and `tree.ngfactory.ts`).
- helper methods `createElementAndAppend` / `createTextAndAppend` / `createAnchorAndAppend`
- remove `injectorGetInternal` assuming we can detect that nobody is injecting an `Injector`
## Properties
- no allocation of arrays nor closures
## Background: why `visitRootNodes`?
* An embedded view has root nodes that need to be attached / detached
to the DOM when the view is inserted.
* An embedded view can have view containers as root nodes. I.e. the root nodes
of a view need to include the root nodes of all views in root view containers
* An embedded view can have `<ng-content>` as root nodes. I.e. the root
nodes of a view need to include the projects nodes, which can
include a view container, in which case they need to include the root nodes
of all included views as well.
Previous implementation:
The generated view classes would store a (possible nested) array of root nodes
that can contain regular DOM nodes as well as ViewContainers.
The helper method `flattenNestedViewRootNodes` is used to convert this array
into a flat array of node.
However, this generates a new array and is probably hard to optimize for
a vm.
### Solution
Generate loop functions / methods.
I.e. a method like:
```
loopRootNodes(cb: (obj: any, ctx: any), ctx: any) {
cb(this.node0, ctx);
...
}
```
These methods can easily be nested, i.e. a view container
can just loop over its views and call this method,
forwarding the callback!
Same is true for projection!
==> Tried it, no impact on the benchmark!
### Discarded Solution 1)
Generate `attach` / `detach` method on EmbeddedView,
which will `insertBefore` the root nodes. Also
generate `project` and `unproject` methods in the caller
of a component to add / remove nodes.
Problems:
- generates a lot of code!
- projected nodes can only be inserted into the DOM via
`insertBefore`, but never via `appendChild` as
the generated method `project` does it,
and it can do only one of these two, but not both.
### Discarded Solution 2)
Generate a method `rootNodes` on every view that will
do produce a flattened array of nodes by generating the
right `concat` statements.
Problems:
- allocates arrays and `concat` calls that slows things down
(an experiment showed about about 2-5%).
## Experiments tried
- just the fact of having another base class in the prototype chain
is not a problem!
- Using a linked list over the views vs an array in ViewContainerRef
has no impact on performance, given that we use `Array.prototype.push`
for adding if possible (only tried with ngIf though...)
* Using `Array.prototype.splice` to add made benchmark 2% slower though!
- creating an array with root nodes does not make the benchmark much slower.
* Using `flattenNestedViewRootNodes` made it 5-10% slower!
* Note that this benchmark only includes `NgIf`, i.e. it only
inserts 1 entry into the array.
- creating an additional comment node for the view container,
so it is safe to do `insertBefore`
* this slows the benchmark down by 14% (added 2 comment nodes)!
==> the number of comment nodes is important!
## Open experiments:
- using ViewRef as a separate wrapper, compared to
using the view itself as ref.
- using AppElement with an injector, native node, ...,
compared to not having all of these fields
- using `insertAfter` instead of `insertBefore`?
## Initial resuls: size
File size for view class of the component + the 2 embedded view classes (without imports nor host view factory):
* before: 140 LOC
* after: 104 LOC
## Initial results: Deep Tree Benchmark

# Ng2 Static Faster Than BaseLine (FTL) Benchmark
This benchmark was produced in the following way:
1. Run AoT over the root component, one branch component
and the leaf component of the ng2_static benchmark
2. Move all 3 component classes to `tree.ts`
3. Add a `depth` property to the view factory constructor of
the `TreeBranchComponent` and pass it down to nested view factory calls
to be able to use the same view factory for all
nesting levels. This is just to make the experiment simpler to not
need to change so much code.
4. Optimize the `tree_branch.ngfactory.ts` and `tree_leaf.ngfactory.ts`
(see below)
The goal of this benchmark is to explore what kind of
code the Ng2 compiler should generate in order to get faster.
I.e. right now, the Ng2 compiler _does not_ produce this kind of code,
but hopefully will in the future.
## Optimizations and cleanups
See `tree_branch.ngfactory.ts` and `tree_leaf.ngfactory.ts`.
Performance:
- remove view factory functions, call the constructor of the view class directly
- remove `createInternal` and move the logic into the constructor
- remove `AppView` parent class
- generate direct calls to `detectChangesInternal` / `destroyInternal` of nested components
- remove `Renderer` and `SanitizationService` to update
the dom directly via `document.createElement` / `element.appendChild` / setting
`Text.nodeValue` / `Element.style....`
- remove `AppElement`
- create component instance in view constructor
Code size:
- helper methods `createElementAndAppend` / `createTextAndAppend` / `createAnchorAndAppend`
- wrap dirty check for `TreeComponent.data` into the method `updateData`
in the view class
- remove `injectorGetInternal` assuming we can detect that nobody is injecting an `Injector`
## Initial results: File size
File size for view class of the component (without imports nor host view factory):
* before: 81 LOC
* after: 53 LOC
