Summary:
Ideally CompilerType would have no knowledge of clang or any individual
TypeSystem. Decoupling clang is relatively straightforward.

Summary:
According to [C128] "Virtual functions should specify exactly one
of `virtual`, `override`, or `final`", I've added override where a
virtual function is overriden but the explicit `override` keyword
was missing. Whenever both `virtual` and `override` were specified,
I removed `virtual`. As C.128 puts it:
> [...] writing more than one of these three is both redundant and
> a potential source of errors.
I anticipate a discussion about whether or not to add `override` to
destructors but I went for it because of an example in [ISOCPP1000].
Let me repeat the comment for you here:
Consider this code:
```
struct Base {
virtual ~Base(){}
};
struct SubClass : Base {
~SubClass() {
std::cout << "It works!\n";
}
};
int main() {
std::unique_ptr<Base> ptr = std::make_unique<SubClass>();
}
```
If for some odd reason somebody removes the `virtual` keyword from the
`Base` struct, the code will no longer print `It works!`. So adding
`override` to destructors actively protects us from accidentally
breaking our code at runtime.

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.

In January Davide sent an e-mail to the mailing list to suggest removing
unmaintained language plugins such as Go and Java. The plan was to have
some cool down period to allow users to speak up, however after that the
plugins were never actually removed.
This patch removes the Go debugger plugin.
The plugin can be added again in the future if it is mature enough both
in terms of testing and maintenance commitment.

This patch extends the FileSystem class with a bunch of functions that
are currently implemented as methods of the FileSpec class. These
methods will be removed in future commits and replaced by calls to the
file system.
The new functions are operated in terms of the virtual file system which
was recently moved from clang into LLVM so it could be reused in lldb.
Because the VFS is stateful, we turned the FileSystem class into a
singleton.

We currently had a 2-step process where we had to call
SetBaseClassesForType and DeleteBaseClasses. Every single caller
followed this exact 2-step process, and there was manual memory
management going on with raw pointers. We can do better than this
by storing a vector of unique_ptrs and passing this around.
This makes for a cleaner API, and we only need to call one method
so there is no possibility of a user forgetting to call
DeleteBaseClassSpecifiers.
In addition to this, it also makes for a *simpler* API. Part of
why I wanted to do this is because when I was implementing the native
PDB interface I had to spend some time understanding exactly what I
was deleting and why. ClangAST has significant mental overhead
associated with it, and reducing the API surface can go along
way to making it simpler for people to understand.

Summary: We can't use unique_ptr's here because we use those variables as `out` parameters to some functions. Discovered by the memory sanitizer.

Summary:
llvm::APSInt(0) asserts because it creates an int with bit-width 0 and
not (as I thought) a value 0.
Theoretically it should be sufficient to change this to APSInt(1), as
the intention there was that the value of the first argument should be
ignored if the type is invalid, but that would look dodgy.
Instead, I use llvm::Optional to denote an invalid value and use a
special struct instead of a std::pair, to reduce typing and increase
clarity.

Summary:
Despite it's name, GetTemplateArgument was only really working for Type
template arguments. This adds the ability to retrieve integral arguments
as well (which I've needed for the std::bitset data formatter).
I've done this by splitting the function into three pieces. The idea is
that one first calls GetTemplateArgumentKind (first function) to
determine the what kind of a parameter this is. Based on that, one can
then use specialized functions to retrieve the correct value. Currently,
I only implement two of these: GetTypeTemplateArgument and
GetIntegralTemplateArgument.

*** to conform to clang-format’s LLVM style. This kind of mass change has
*** two obvious implications:
Firstly, merging this particular commit into a downstream fork may be a huge
effort. Alternatively, it may be worth merging all changes up to this commit,
performing the same reformatting operation locally, and then discarding the
merge for this particular commit. The commands used to accomplish this
reformatting were as follows (with current working directory as the root of
the repository):
find . \( -iname "*.c" -or -iname "*.cpp" -or -iname "*.h" -or -iname "*.mm" \) -exec clang-format -i {} +
find . -iname "*.py" -exec autopep8 --in-place --aggressive --aggressive {} + ;
The version of clang-format used was 3.9.0, and autopep8 was 1.2.4.
Secondly, “blame” style tools will generally point to this commit instead of
a meaningful prior commit. There are alternatives available that will attempt
to look through this change and find the appropriate prior commit. YMMV.

In doing so, two bugs were uncovered (and fixed). The first bug
is that ClangASTContext::RemoveFastQualifiers() was broken, and
was not removing fast qualifiers (or doing anything else for that
matter). The second bug is that UnifyAccessSpecifiers treated
AS_None asymmetrically, which is probably an edge case, but seems
like a bug nonetheless.
