to reflect the new license.
We understand that people may be surprised that we're moving the header
entirely to discuss the new license. We checked this carefully with the
Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM
project under our new license, so you will see that the license headers
include that license only. Some of our contributors have contributed
code under our old license, and accordingly, we have retained a copy of
our old license notice in the top-level files in each project and
repository.

Summary:
We fail to import a `ClassTemplateDecl` if the "To" context already
contains a definition and then a forward decl. This is because
`localUncachedLookup` does not find the definition. This is not a
lookup error, the parser behaves differently than assumed in the
importer code. A `DeclContext` contains one DenseMap (`LookupPtr`)
which maps names to lists. The list is a special list `StoredDeclsList`
which is optimized to have one element. During building the initial
AST, the parser first adds the definition to the `DeclContext`. Then
during parsing the second declaration (the forward decl) the parser
again calls `DeclContext::addDecl` but that will not add a new element
to the `StoredDeclsList` rarther it simply overwrites the old element
with the most recent one. This patch fixes the error by finding the
definition in the redecl chain. Added tests for the same issue with
`CXXRecordDecl` and with `ClassTemplateSpecializationDecl`. These tests
pass and they pass because in `VisitRecordDecl` and in
`VisitClassTemplateSpecializationDecl` we already use
`D->getDefinition()` after the lookup.

Add a helper test Fixture, so we can add tests which can check internal
attributes of AST nodes like getPreviousDecl(), isVirtual(), etc.
This enables us to check if a redeclaration chain is correctly built during
import, if the virtual flag is preserved during import, etc. We cannot check
such attributes with the existing testImport.
Also, this fixture makes it possible to import from several "From" contexts.
We also added several test cases here, some of them are disabled.
We plan to pass the disabled tests in other patches.
