RFR: 8264626: C1 should be able to inline excluded methods

[Nils Eliasson]

I noticed a behavioral between c1 and c2. In c2 excluded methods can still be inlined, which is the desired behaviour. Inlining is controlled separately. I propose a small change to c1 inlining that make it work in the same way.
