In the case of a function constructor or eval, we create a new script object which doesn't have a script name. In this case, we traverse upwards on the list of SFI's through script->eval_from_shared() to get the outermost script that was not an eval script and get the script name from that script.

Port c820b89b Original Commit Message: Removes the new.target slot from the interpreter's fixed frame. Instead adds a field to BytecodeArray to get the bytecode's incoming new.target or generator object register. The InterpreterEntryTrampoline then sets this register with the incoming new.target (or generator object) when the function is called. This register can be directly the new.target or generator object variable if they are LOCAL location, otherwise it is a temporary register which is then moved to the variable's location during the function prologue. This fixes a hack in the deoptimizer where we would set the new.target fixed slot to undefined in order to avoid extending it's lifetime through the optimized code - now it's just a standard register and can be optimized away as normal.

Splits CompileUnoptimizedCode into a non-main thread GenerateUnoptimizedCode and a main thread FinalizeUnoptimizedCode phase. Adds Disallow<HeapAccess> scopes in CompileUnoptimizedCode to ensure no access to the heap during this phase. Also cleans up a few heap accesses in CompilationInfo's constructor to avoid violating the disallowed heap access. Currently we reallow heap access during asm.js compilation as a temporary measure until the script streamer uses an off-heap script buffer.

This follows up 4af9cfcc by separating incremental marking state from the full MC marking state. Runtime and tests now use only the incremental marking state. The full MC marking state used by MC during atomic pause. This separation decouples atomicity of markbit accesses during incremental marking and during full MC.
