Michael Starzinger 9d23ec9f69 [turbofan] Remove deoptimization support from AstGraphBuilder. 
The AST-based graph builder is by now only used for asm.js code. This
change hard-codes this assumption into the compilation pipeline and
hence allows us to remove support pertaining to deoptimization from
optimized code that was not derived from bytecode.
