Erich Keane babdef27c5 Re-apply "Deferred Concept Instantiation Implementation"
This reverts commit 95d94a6775.

This implements the deferred concepts instantiation, which should allow
the libstdc++ ranges to properly compile, and for the CRTP to work for
constrained functions.

Since the last attempt, this has fixed the issues from @wlei and
@mordante.

Erich Keane 95d94a6775 Revert "Re-apply "Deferred Concept Instantiation Implementation"""
This reverts commit d483730d8c.

This allegedly breaks a significant part of facebooks internal build.
Reverting while we wait for them to provide a reproducer of this from
@wlei.

Erich Keane d483730d8c Re-apply "Deferred Concept Instantiation Implementation""
This reverts commit 258c3aee54.

This should fix the libc++ issue that caused the revert, by re-designing
slightly how we determined when we should evaluate the constraints.
Additionally, many of the other components to the original patch (the
NFC parts) were committed separately to shrink the size of this patch
for review.

This reverts commit befa8cf087.

Apparently this breaks some libc++ builds with an apparent assertion,
 so I'm looking into that .

This reverts commit d4d47e574e.

This fixes the lldb crash that was observed by ensuring that our
friend-'template contains reference to' TreeTransform properly handles a
TemplateDecl.

Revert "Deferred Concept Instantiation Implementation"
This reverts commit 2f20743952 because it
triggers an assertion when building an LLDB test program:

  Assertion failed: (InstantiatingSpecializations.empty() && "failed to
  clean up an InstantiatingTemplate?"), function ~Sema, file
  /Users/buildslave/jenkins/workspace/lldb-cmake/llvm-project/clang/lib/Sema/Sema.cpp,
  line 458.

Erich Keane 2f20743952 Deferred Concept Instantiation Implementation
This is a continuation of D119544.  Based on @rsmith 's feed back
showing me https://eel.is/c++draft/temp#friend-9, We should properly
handle friend functions now.

This reverts commit a425cac31e.

There is another libc++ test, that this time causes us to hit an
assertion. Reverting, likely for a while this time.

Erich Keane a425cac31e "Re-apply 4b6c2cd642 "Deferred Concept Instantiation Implementation""""
This includes a fix for the libc++ issue I ran across with friend
declarations not properly being identified as overloads.

This reverts commit 45c07db31c.

Erich Keane 45c07db31c Revert "Re-apply 4b6c2cd642 "Deferred Concept Instantiation Implementation"""
This reverts commit a97899108e.

The patch caused some problems with the libc++ `__range_adaptor_closure`
that I haven't been able to figure out the cause of, so I am reverting
while I figure out whether this is a solvable problem/issue with the
  CFE, or libc++ depending on an older 'incorrect' behavior.

Erich Keane a97899108e Re-apply 4b6c2cd642 "Deferred Concept Instantiation Implementation""
This reverts commit 0c31da4838.

I've solved the issue with the PointerUnion by making the
`FunctionTemplateDecl` pointer be a NamedDecl, that could be a
`FunctionDecl` or `FunctionTemplateDecl` depending.  This is enforced
with an assert.

Erich Keane 0c31da4838 Revert "Deferred Concept Instantiation Implementation"
This reverts commit 4b6c2cd647.

The patch caused numerous ARM 32 bit build failures, since we added a
5th item to the PointerUnion, and went over the 2-bits available in the
32 bit pointers.

Erich Keane 4b6c2cd647 Deferred Concept Instantiation Implementation
As reported here: https://github.com/llvm/llvm-project/issues/44178

Concepts are not supposed to be instantiated until they are checked, so
this patch implements that and goes through significant amounts of work
to make sure we properly re-instantiate the concepts correctly.
