Fixes#7315
BREAKING CHANGES:
Previously multiple template bindings on one element
(ex. `<div *ngIf='..' *ngFor='...'>`) were allowed but most of the time
were leading to undesired result. It is possible that a small number
of applications will see template parse errors that shuld be fixed by
nesting elements or using `<template>` tags explicitly.
Closes#9462
Fix how the compiler checks for recursive components by also considering
component descendants. Previously, it only checked if the current
component was evaluated previously. This failed in certain cases of
mutually recursive components, causing `createAsync` in tests to not
resolve.
closes [7084](https://github.com/angular/angular/issues/7084)
After splitting the facades into multiple modules,
enabling prod mode for code had no effect for the compiler.
Also in a change between RC1 and RC2 we created the `CompilerConfig`
via a provider with `useValue` and not via a `useFactory`, which reads
the prod mode too early.
