Allow full inlining of f.apply(this, arguments) calls.

Allow full inlining of f.apply(this, arguments) calls.

This allows Crankshaft to completely inline a f.apply() dispatch if the
exact number of arguments is known and the function is constant. The
deoptimizer doesn't generate the f.apply() frame during deoptimization,
so the materialized frames look like f.apply() did a tailcall.

Note that this is a bug that is already present in our current optimization and
is not introduced by this change. This test just flushed it out.
