In CL 327872, there's a fix for crawling of embeddable types directly
reached by the user, so all of its methods need to be re-exported. But
we missed the cased when an un-exported type may be reachable by
embedding in exported type. Example:
type t struct {}
func (t) M() {}
func F() interface{} { return struct{ t }{} }
We generate the wrapper for "struct{ t }".M, and when inlining call to
"struct{ t }".M makes "t.M" reachable.
It works well, and only be revealed in CL 327871, when we changed
methodWrapper to always call inline.InlineCalls, thus causes the crash
in #49016, which involve dot type in inlined function.
Fixes #49016
