Do not call ResolveCompileInstanceFunction from the lookup stub.

Do not call ResolveCompileInstanceFunction from the lookup stub.

The InstanceFunctionLookup stub is only called after the inline cache miss
handler.  The miss handler ensures that ResolveCompileInstanceCallTarget is
called.

There was a weird permutation of the IC data and arguments descriptor registers
on both platforms.  It seems gratuitous, and I removed it.

I don't fully understand the difference between ResolveImplicitClosureFunction
and ResolveImplicitClosureThroughGetter to ensure that we have explicit test
coverage.  I will put a debug break in those places to verify that they are hit
by our tests.
