  [FuncSpec] Do not specialize interposable functions (#204314)

We cannot specialize interposable functions, because the definition we
see may not be prevailing one. The prevailing definition can have
arbitrary different behavior.

We *can* still specialize inexact definitions like linkonce_odr, similar
to inlining.
