This change unifies the logic for template instantiation of methods and
functions declared with typedefs.
It ensures that SubstFunctionType() always fills the Params out param
with non-null ParmVarDecls or returns null.

There seems to be a crash here if we have a calling convention attribute
that gets ignored and then we instantiate templates.

Canonical types are unchanged. The type printer had to be changed to
avoid printing any non-default implicit calling convention as well as
the calling convention attribute.

also instantiate the synthesized function parameters for the resulting
function declaration.
With this change, Boost.Wave builds and passes all of its regression
tests.

of the mapping from local declarations to their instantiated
counterparts during template instantiation. Previously, we tried to do
some unholy merging of local instantiation scopes that involved
storing a single hash table along with an "undo" list on the
side... which was ugly, and never handled function parameters
properly.
Now, we just keep separate hash tables for each local instantiation
scope, and "combining" two scopes means that we'll look in each of the
combined hash tables. The combined scope stack is rarely deep, and
this makes it easy to avoid the "undo" issues we were hitting. Also,
I've simplified the logic for function parameters: if we're declaring
a function and we need the function parameters to live longer, we just
push them back into the local instantiation scope where we need them.
Fixes PR6990.

complete, return an error rather than falling back to building a
dependent declaration reference, since we might not be in a dependent
context. Fixes a fiendish crash-on-invalid in Boost.FunctionTypes that
I wasn't able to reduce to anything useful.

Declarator that depends on it. This fixes several redundant errors and bad
recoveries.

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.

- 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.
