PR c++/85214 - ICE with alias, generic lambda, constexpr if.
Here, since the condition for the constexpr if depends on the type of 'j',
it's still dependent when we are partially instantiating the inner lambda,
so we need to defer instantiating the constexpr if. When we instantiated
the inner lambda, we tried to substitute into the typename, which failed
because we didn't have a declaration of 'i' available.
Fixed by teaching extract_locals_r to capture local typedefs such as 'ar';
if we have the typedef handy, we don't need to substitute into its
definition.

C++: more std header hints; filter on C++ dialect (PR c++/84269)
This patch adds more suggestions as per:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=84269#c10
some of which need C++14 and C++17, and some of which use headers that
exist in earlier standards.
For example, <memory> exists in C++98, but if the user attempts to
use std::make_shared with -std=c++98, they are suggested to include
<memory>, even if they've already included it.
This patch adds the missing names, and fixes the nonsensical suggestions
by detecting if the name isn't available yet, based on the user's
dialect, and reporting things more intelligently:
t.cc: In function 'void test_make_shared()':
t.cc:5:8: error: 'make_shared' is not a member of 'std'
std::make_shared<int>();
^~~~~~~~~~~

[PR c++/84979] reject auto in explicit tmpl args for tmpl-fn
With concepts, we accept auto in explicit template arguments, but we
should only accept them for template classes. Passing them to
template functions or variables is not allowed. So, reject it, at
parse time if possible, at specialization time otherwise.
