Change the compiler's DWARF inline info generation to be more careful about producing consistent instances of abstract function DIEs. The new strategy is to insure that the only params/variables created in an abstract subprogram DIE are those corresponding to declarations in the original pre-inlining version of the code. If a concrete subprogram winds up with other vars as part of the compilation process (return temps, for example, or scalars generated by splitting a structure into pieces) these are emitted as regular param/variable DIEs instead of concrete DIEs. The linker dwarf test now has a couple of new testpoints that include checks to make sure that all abstract DIE references are sane/resolvable; this will help catch similar problems in the future. Fixes #23046.
