[dev.link] cmd/internal/obj, cmd/link: add InlTree in new object files

Browse source 
Add InlTree to the FuncInfo aux symbol in new object files.

In the linker, change InlinedCall.Func from a Symbol to a string,
as we only use its Name. (There was a use of Func.File, but that
use is not correct anyway.) So we don't need to create a Symbol
if not necessary.
