require paths passed to be separated by '/' instead of being
able to handle '\'.
`ngc` and `ng` already do this transformation.
Fixes: #21811
PR Close#21812
Usages of `NgTools_InternalApi_NG_2` from `@angular/compiler-cli` will now

Adds `listLazyRoutes` to `@angular/compiler-cli/ngtools2.ts` for getting
the lazy routes of a `ng.Program`.

- temporarily keeps the old sources under packages/tsc-wrapped
until the build scripts are changed to use compiler-cli everywhere.
- removes the compiler options `disableTransformerPipeline` that was introduced
in a previous beta of Angular 5, i.e. the transformer based compiler
is now always enabled.
PR Close#18966
Removes the tsickle dependency added when tsickle was added to the
transform compiler.
Added a test to ensure stray dependencies are not added and no
errors are introduced during module flattening.
Reworked some of the code so asserts are no longer necessary.
Added additional and potentially redundant checks
Added checks where the null checker found real problems.
