[PATCH c++/86881] -Wshadow-local-compatible ICE

[Nathan Sidwell]

This ICE happens when we try and figure if an unresolved auto type is 
compatible with a previous binding.  With the addition of auto, we're 
now checking too early, but that's a harder problem.   This fixes the 
ICE, but the downside is we don't warn at all, if the auto resolves to a 
compatible type.  But that's not a new problem.

Applying to trunk and gcc-8
