Support inlining detection from debugger.

In the context of the compiler, every method and field should be resolved. The
InlineMethodAnalyser uses that property so we don't inline unresolved methods
or methods accessing unresolved fields. In the context of the debugger, this is
not true. We may install a breakpoint in a method that's never been resolved
yet for instance.

This CL weaks that property so we can detect getter/setter methods can be
inlined even if they're not resolved yet. To differentiate both contexts, we
pass a null inline method pointer to InlineMethodAnalyser::AnalyseIGetMethod.
