Remove --stop-at flag from several backends.

Remove --stop-at flag from several backends.

The flag in question is a debug-only flag supported by full-codegen and
Crankshaft only. In it's current form there are some unresolved issues:
- The flag is defeated by inlining in Crankshaft.
- The flag is not supported by TurboFan.
- The flag is not supported by Ignition.

Instead of addressing the above issues and increasing maintenance cost
for all backends and also given the "slim" test coverage, this CL fully
removes the support from all backends.
