Fix illegal inlining of instructions accessing protected members

There were two issues in the new inliner that would cause a
VerifyError and an IllegalAccessError.

First, an access to a public member of package protected class C can
only be inlined if the destination class can access C. This is tested
by t7582b.

Second, an access to a protected member requires the receiver object
to be a subtype of the class where the instruction is located. So
when inlining such an access, we need to know the type of the receiver
object - which we don't have. Therefore we don't inline in this case
for now. This can be fixed once we have a type propagation analyis.

This case is tested by t2106.

Force kmpSliceSearch test to delambdafy:inline

See discussion on https://github.com/scala/scala/pull/4505. The issue
will go away when moving to indy-lambda.
