[turbofan] Initial support for constructor call inlining.

[turbofan] Initial support for constructor call inlining.

This implements a first version of support for constructor call inlining
in the inlining machinery. For now we can only inline calls where the
actual constructor and the original constructor coincide (i.e. no super
constructor calls). Note that the target of a super constructor call is
loaded with a runtime call, so there is no way for it to be constant
promoted at the moment.
