Jaroslav Sevcik 6e8c00f7df Introduce an Abort bytecode and turbofan operator. 
The advantage of an explicit Abort that the interpreter and the compiler know
that aborting cannot continue or throw or deopt. As a result we generate less
code and we do not confuse the compiler if the environment is not set up for
throwing (as in the generator dispatch that fails validation in
crbug.com/762057).
