This makes sure that inlining a constructor call to a function which
cannot be used as a constructor (e.g. strong mode function) still does
throw correctly when the implicit receiver is created.

The %_CallFunction doesn't implement the call sequence properly, it
doesn't do the receiver wrapping, nor does it check for
classConstructor. Also the eager deoptimization for %_CallFunction was
seriously b0rked (we must have been lucky with TurboFan so far).

This fixes [NAMED|KEYED]_SUPER_PROPERTY_CALL to perform a method call
instead of a function call. The difference is visible for sloppy mode

This refactors the handling of calls of type Call::PROPERTY_CALL to
super properties in AstGraphBuilder::VisitCall. It ensures that the
operand stack is kept in sync with full-codegen so that deopts while
evaluating sub-expressions behave as expected.

This fixes a missing SSA-renaming of the callee value used in the frame
state of a call node. An OSR-entry within do-expressions contained in
one of the argument expression can trigger that renaming.

Previously ChangeLowering would always box float64 values when going to
tagged representation, but that introduces a lot of deoptimizer loops
and polymorphism into TurboFan, which is unfortunate and unnecessary.
This adds some logic to ChangeFloat64ToTagged to try harder to create a
Smi when going from Float64 to Tagged, instead of always allocating a
HeapNumber. This might need some additional tweaking, but at least it
makes it possible to start comparing TurboFan and Crankshaft for some
regular JavaScript.

This fixes the representation type for values in JSArray::length fields
when JSNativeContextSpecialization lowers loads. Only arrays with fast
elements kind are guaranteed to have a Smi represented length.

It is not always safe to allocate new heap objects in the JSGraph. We
might have to revisit this later once we do the canonicalization for
HeapConstants.

This introduces an explicit lazy bailout. It is wrapped in the call
node, mostly because the lazy deoptimization processing is married
to the call processing in the instruction selector and the code generator.
It is still a terrible hack.
