Top left and top right for big FABs, and top left for mini FABs.

Also, some code cleanup.

* Renamed --save-compilation-trace to flutter run --train.
* Renamed --precompile=<file> to --compilation-trace-file=<file>.
* In dynamic mode, made JIT snapshot the default, instead of kernel file.

It's easier to run the android_views integration test this way, without
needing to worry if we have a local clone of the goldens repo or not.

We have a page on the Web page now.
