Summary:
The FileID/Offset conversion is lossy. The code takes the fileLoc, which loses
e.g. the spelling location in some macro cases.
Instead, pass the original SourceLocation which preserves all information, and
update consumers to match current behavior.
This allows us to fix two bugs in clangd that need the spelling location.

I presume WorkingDir is somehow changed to /usr/lib or /usr/include and
clang_getFileName() returns a path relative to WorkingDir.
clang_File_tryGetRealPathName() returns "/usr/include/c++/7.3.0/string"
which is more useful for the indexer in this case.

-cc1gen-reproducer driver option
The recommit fixes:
- An MSAN failure (CCPrintOptions wasn't initialized in the Driver)
- Ensures that the strings in the libclang invocation files are escaped
Original message:
This commit is a follow up to the previous work that recorded Libclang invocations
into temporary files: r319702.
It adds a new -cc1 mode to clang: -cc1gen-reproducer. The goal of this mode is to generate
Clang reproducer files for Libclang tool invocation. The JSON format in the invocation
files is not really intended to be stable, so Libclang and Clang should be of the same version
when generating reproducers.
The new mode emits the information about the temporary files and Libclang-specific information
to stdout using JSON.

Summary:
`ASTPrinter` allows setting the ouput to any O-Stream, but that printer creates source-code-like syntax (and is also marked with a `FIXME`). The nice, colourful, mostly human-readable `ASTDumper` only works on the standard output, which is not feasible in case a user wants to see the AST of a file through a code navigation/comprehension tool.
This small addition of an overload solves generating a nice colourful AST block for the users of a tool I'm working on, [[ http://github.com/Ericsson/CodeCompass | CodeCompass ]], as opposed to having to duplicate the behaviour of definitions that only exist in the anonymous namespace of implementation TUs related to this module.

We currently use target_link_libraries without an explicit scope
specifier (INTERFACE, PRIVATE or PUBLIC) when linking executables.
Dependencies added in this way apply to both the target and its
dependencies, i.e. they become part of the executable's link interface
and are transitive.
Transitive dependencies generally don't make sense for executables,
since you wouldn't normally be linking against an executable. This also
causes issues for generating install export files when using
LLVM_DISTRIBUTION_COMPONENTS. For example, clang has a lot of LLVM
library dependencies, which are currently added as interface
dependencies. If clang is in the distribution components but the LLVM
libraries it depends on aren't (which is a perfectly legitimate use case
if the LLVM libraries are being built static and there are therefore no
run-time dependencies on them), CMake will complain about the LLVM
libraries not being in export set when attempting to generate the
install export file for clang. This is reasonable behavior on CMake's
part, and the right thing is for LLVM's build system to explicitly use
PRIVATE dependencies for executables.
Unfortunately, CMake doesn't allow you to mix and match the keyword and
non-keyword target_link_libraries signatures for a single target; i.e.,
if a single call to target_link_libraries for a particular target uses
one of the INTERFACE, PRIVATE, or PUBLIC keywords, all other calls must
also be updated to use those keywords. This means we must do this change
in a single shot. I also fully expect to have missed some instances; I
tested by enabling all the projects in the monorepo (except dragonegg),
and configuring both with and without shared libraries, on both Darwin
and Linux, but I'm planning to rely on the buildbots for other
configurations (since it should be pretty easy to fix those).
Even after this change, we still have a lot of target_link_libraries
calls that don't specify a scope keyword, mostly for shared libraries.
I'm thinking about addressing those in a follow-up, but that's a
separate change IMO.

Storing the contents of unsaved files is too expensive.
Instead a hash is stored with a record invocation. When a reproducer is
generated, Clang will compare the stored hashes to the new hashes to determine
if the contents of a file has changed. This way we'll know when a reproducer was
generated for a different source to the one that triggered the original crash.

o) Add a 'Location' class that represents the four properties of a
physical location
o) Enhance 'SourceLocation' to provide 'expansion' and 'spelling'
locations, maintaining backwards compatibility with existing code by
forwarding the four properties to 'expansion'.
o) Update the implementation to use 'clang_getExpansionLocation'
instead of the deprecated 'clang_getInstantiationLocation', which
has been present since 2011.
o) Update the implementation of 'clang_getSpellingLocation' to actually
obtain spelling location instead of file location.

Summary:
Change clang-refactor default behavior to print the new code after refactoring
(instead of editing the source files), which would make it easier to use
and debug the refactoring action.

It'd be better that they are #cmakedefine01 rather than #cmakedefine.
(#if FOO rather than #if defined(FOO))
Then we can find missing #include "clang/Config/config.h" in the future.

Summary: Previously, `VisitAttributes` was not called for function and class templates and thus their attributes were not accessible using libclang.

This commit allows the refactoring library to use its own set of
refactoring-specific diagnostics to reports things like initiation errors.

The fixed commit ensures that ParsedSourceRange works correctly
with Windows paths.
Original message:
This commit actually brings clang-refactor to a usable state as it can now
apply the refactoring changes to source files.
The -selection option is now also fully supported.

Summary:
Convert clang::LangAS to a strongly typed enum
Currently both clang AST address spaces and target specific address spaces
are represented as unsigned which can lead to subtle errors if the wrong
type is passed. It is especially confusing in the CodeGen files as it is
not possible to see what kind of address space should be passed to a
function without looking at the implementation.
I originally made this change for our LLVM fork for the CHERI architecture
where we make extensive use of address spaces to differentiate between
capabilities and pointers. When merging the upstream changes I usually
run into some test failures or runtime crashes because the wrong kind of
address space is passed to a function. By converting the LangAS enum to a
C++11 we can catch these errors at compile time. Additionally, it is now
obvious from the function signature which kind of address space it expects.
I found the following errors while writing this patch:
- ItaniumRecordLayoutBuilder::LayoutField was passing a clang AST address
space to TargetInfo::getPointer{Width,Align}()
- TypePrinter::printAttributedAfter() prints the numeric value of the
clang AST address space instead of the target address space.
However, this code is not used so I kept the current behaviour
- initializeForBlockHeader() in CGBlocks.cpp was passing
LangAS::opencl_generic to TargetInfo::getPointer{Width,Align}()
- CodeGenFunction::EmitBlockLiteral() was passing a AST address space to
TargetInfo::getPointerWidth()
- CGOpenMPRuntimeNVPTX::translateParameter() passed a target address space
to Qualifiers::addAddressSpace()
- CGOpenMPRuntimeNVPTX::getParameterAddress() was using
llvm::Type::getPointerTo() with a AST address space
- clang_getAddressSpace() returns either a LangAS or a target address
space. As this is exposed to C I have kept the current behaviour and
added a comment stating that it is probably not correct.
Other than this the patch should not cause any functional changes.

The recommit fixes a UB bug that occurred only on a small number of bots.
Original message:
This commit adds initial support for refactoring options. One can now use
optional and required std::string options.
This commit also adds a NewNameOption for the local-rename refactoring action to
allow rename to work with custom names.
