Async functions are built out of generators, but the
SharedFunctionInfo returns false for is_generator. is_resumable is
the broader query. This patch fixes many parts of V8 to refer
to is_resumable as appropriate.
One incidental change is to remove a check for generators extending
classes. This is part of a general check for constructors being the
only thing which can extend classes, so it is removed here and the
error message for the general case is made more accurate.

A sloppy mode eval call that establishes strict mode will leak that strictness
into the sloppy surrounding scope on recompile. This changes the structure
of the type feedback vector for the function and crashes follow.
The fix is straightforward.
