Summary:
Support functions with placeholder return types even in cases when the type is
declared in the body of the function.
Example: auto f() { struct X{}; return X(); }

Summary:
When Sema encounters a ObjCMethodDecl definition it declares the implicit parameters for the ObjCMethodDecl.
When importing such a method with the ASTImporter we need to do the same for the imported method
otherwise we will crash when generating code (where CodeGen expects that this was called by Sema).
Note I had to implement Objective-C[++] support in Language.cpp as this is the first test for Objective-C and this
would otherwise just hit this 'not implemented' assert when running the unit test.

This caused Clang to start erroring on the following:
struct S {
template <typename = int> explicit S();
};
struct T : S {};
struct U : T {
U();
};
U::U() {}
$ clang -c /tmp/x.cc
/tmp/x.cc:10:4: error: call to implicitly-deleted default constructor of 'T'
U::U() {}
^
/tmp/x.cc:5:12: note: default constructor of 'T' is implicitly deleted
because base class 'S' has no default constructor
struct T : S {};
^
1 error generated.

this patch adds support for the explicit bool specifier.
Changes:
- The parsing for the explicit(bool) specifier was added in ParseDecl.cpp.
- The storage of the explicit specifier was changed. the explicit specifier was stored as a boolean value in the FunctionDeclBitfields and in the DeclSpec class. now it is stored as a PointerIntPair<Expr*, 2> with a flag and a potential expression in CXXConstructorDecl, CXXDeductionGuideDecl, CXXConversionDecl and in the DeclSpec class.
- Following the AST change, Serialization, ASTMatchers, ASTComparator and ASTPrinter were adapted.
- Template instantiation was adapted to instantiate the potential expressions of the explicit(bool) specifier When instantiating their associated declaration.
- The Add*Candidate functions were adapted, they now take a Boolean indicating if the context allowing explicit constructor or conversion function and this boolean is used to remove invalid overloads that required template instantiation to be detected.
- Test for Semantic and Serialization were added.
This patch is not yet complete. I still need to check that interaction with CTAD and deduction guides is correct. and add more tests for AST operations. But I wanted first feedback.
Perhaps this patch should be spited in smaller patches, but making each patch testable as a standalone may be tricky.

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:
In order to avoid build failures on MS, we use -fms-compatibility too in
the tests which use the TestBase. Moved the family of `testImport`
functions under a test fixture class, so we can use parameterized tests.
Refactored `testImport` and `testImportSequence`, because `for` loops over
the different compiler options is no longer needed, that is handeld by
the test framework via parameters from now on.

Summary:
This patch add new tests for structural equivalence. For that a new
common header is created which holds the test related language specific
types and functions.
