607f14168a Improve diagnostics when printing a template instantiation backtrace
involving substitution of deduced template arguments into a class
template partial specialization or function template, or when
substituting explicitly-specific template arguments into a function
template. We now print the actual deduced argument bindings so the
user can see what got deduced.

da61afaf9d Improve our handling of local instantiation scopes in two related ways:
- When substituting template arguments as part of template argument
    deduction, introduce a new local instantiation scope.
  - When substituting into a function prototype type, introduce a new
    "temporary" local instantiation scope that merges with its outer
    scope but also keeps track of any additions it makes, removing
    them when we exit that scope.

Fixes PR6700, where we were getting too much mixing of local
instantiation scopes due to template argument deduction that
substituted results into function types.

5112157958 Each non-local class instantiation is its own local instantiation
scope. Fixes PR6619.
