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.

if *none* of the successors of the call expression is the exit block.
This matters when a call of bool type is the condition of (say) a while
loop in a function with no statements after the loop.  This *can* happen
in C, but it's much more common in C++ because of overloaded operators.

originally declared. We use this number so that we can always walk the

poorly in inconsistent ways.

address of an overloaded function (or function template), perform that
resolution prior to determining the implicit conversion
sequence. This resolution is not part of the implicit conversion
sequence itself.

Previously, we would always consider this resolution to be a
function pointer decay, which was a lie: there might be an explicit &
in the expression, in which case decay should not occur. This caused
the CodeGen assertion in PR6973 (where we created a 
pointer to a pointer to a function when we should have had a pointer
to a function), but it's likely that there are corner cases of
overload resolution where this would have failed.

Cleaned up the code involved in determining the type that will
produced afer resolving the overloaded function reference, and added
an assertion to make sure the result is correct. Fixes PR6973.
