Benjamin Kramer e9e7607974 [vfs] Normalize working directory if requested.
FixedCompilationDatabase sets the working dir to "." by default. For
chdir(".") this is a noop but this lead to InMemoryFileSystem to create
bogus paths. Fixes PR25327.

Ben Langmuir f13302e63f [VFS] Fix status() of opened redirected file
Make RedirectedFileSystem::openFilForRead(path)->status() the same as
RedirectedFileSystem::status(path). Previously we would just get the
status of the underlying real file, which would not have the IsVFSMapped
bit set.

This fixes rebuilding a module that has an include that is relative to
the includer where we will lookup the real path of that file before we
lookup the VFS location.

Benjamin Kramer 71ce376b2f [VFS] Let the user decide if they want path normalization.
This is a more principled version of what I did earlier. Path
normalization is generally a good thing, but may break users in strange
environments, e. g. using lots of symlinks. Let the user choose and
default it to on.

This also changes adding a duplicated file into returning an error if
the file contents are different instead of an assertion failure.

Benjamin Kramer 7708b2a4b6 [VFS] Add working directories to every virtual file system.
For RealFileSystem this is getcwd()/chdir(), the synthetic file systems can
make up one for themselves. OverlayFileSystem now synchronizes the working
directories when a new FS is added to the overlay or the overlay working
directory is set. This allows purely artificial file systems that have zero
ties to the underlying disks.

This is a simple file system tree of memory buffers that can be filled by a

There were two issues with the original patch that have now been fixed.
1. We were memset'ing over a FileEntry in a test case. After adding a
   std::string to FileEntry, this still happened to not break for me.
2. I didn't pass the FileManager into the new compiler instance in
   compileModule. This was hidden in some cases by the fact I didn't
   clear the module cache in the test.

Also, I changed the copy constructor for FileEntry, which was memcpy'ing
in a (now) unsafe way.

Ben Langmuir b59cf679e8 Add a 'use-external-names' option to VFS overlay files
When true, sets the name of the file to be the name from
'external-contents'. Otherwise, you get the virtual path that the file
was looked up by. This will not affect any non-virtual paths, or fully
virtual paths (for which there is no reasonable 'external' name anyway).

The setting is available globally, but can be overriden on a per-file
basis.

The goal is that this setting will control which path you see in debug
info, diagnostics, etc. which are sensitive to which path is used. That
will come in future patches that pass the name through to FileManager.

Manuel Klimek 1f76c4e810 Use the same SourceManager for ModuleMaps and compilations.
This allows using virtual file mappings on the original SourceManager to
map in virtual module.map files. Without this patch, the ModuleMap
search will find a module.map file (as the FileEntry exists in the
FileManager), but will be unable to get the content from the
SourceManager (as ModuleMap previously created its own SourceManager).

Two problems needed to be fixed which this patch exposed:

1. Storing the inferred module map
When writing out a module, the ASTWriter stores the names of the files
in the main source manager; when loading the AST again, the ASTReader
errs out if such a file is found missing, unless it is overridden.
Previously CompilerInstance's compileModule method would store the
inferred module map to a temporary file; the problem with this approach
is that now that the module map is handled by the main source manager,
the ASTWriter stores the name of the temporary module map as source to
the compilation; later, when the module is loaded, the temporary file
has already been deleted, which leads to a compilation error. This patch
changes the inferred module map to instead inject a virtual file into
the source manager. This both saves some disk IO, and works with how the
ASTWriter/ASTReader handle overridden source files.

2. Changing test input in test/Modules/Inputs/*
Now that the module map file is handled by the main source manager, the
VerifyDiagnosticConsumer will not ignore diagnostics created while
parsing the module map file. The module test test/Modules/renamed.m uses
-I test/Modules/Inputs and triggers recursive loading of all module maps
in test/Modules/Inputs, some of which had conflicting names, thus
leading errors while parsing the module maps. Those diagnostics already
occur on trunk, but before this patch they would not break the test, as
they were ignored by the VerifyDiagnosticConsumer. This patch thus
changes the module maps that have been recently introduced which broke
the invariant of compatible modules maps in test/Modules/Inputs.

Rafael Espindola f8f91b8976 Use llvm::sys::fs::UniqueID for windows and unix.
This unifies the unix and windows versions of FileManager::UniqueDirContainer
and FileManager::UniqueFileContainer by using UniqueID.

We cannot just replace "struct stat" with llvm::sys::fs::file_status, since we
want to be able to construct fake ones, and file_status has different members
on unix and windows.

What the patch does is:

* Record only the information that clang is actually using.
* Use llvm::sys::fs::status instead of stat and fstat.
* Use llvm::sys::fs::UniqueID
* Delete the old windows versions of UniqueDirContainer and
UniqueFileContainer since the "unix" one now works on windows too.

Rafael Espindola ee30546c00 Fix handling of "clang c:foo"
On windows, c:foo is a valid file path, but stat fails on just "c:". This
causes a problem for clang since its file manager wants to cache data about
the parent directory.

There are refactorings to be done in here, but this gives clang the correct
behavior and testing first.

Jordan Rose a7d03840e6 Excise <cctype> from Clang (except clang-tblgen) in favor of CharInfo.h.

Jordan Rose a2100d755a Pull Lexer's CharInfo table out for general use throughout Clang.
Rewriting the same predicates over and over again is bad for code size and
code maintainence. Using the functions in <ctype.h> is generally unsafe
unless they are specified to be locale-independent (i.e. only isdigit and
isxdigit).

The next commit will try to clean up uses of <ctype.h> functions within Clang.

Chandler Carruth 016bbd88cf Clang side of a refactoring of the CMake unit test build strategy.
The fundamental change is to put a CMakeLists.txt file in the unittest
directory, with a single test binary produced from it. This has several
advantages.

Among other fundamental advantages, we start to get the checking logic
for when a file is missing from the CMake build, and this caught one
missing file already! More fun details in the LLVM commit corresponding
to this one.

Note that the LLVM commit and this one most both be applied, or neither.
Sorry for any skew issues.

Argyrios Kyrtzidis a956450eb7 [preprocessor] Handle correctly inclusion directives that have macro expansions, e.g
"#include MACRO(STUFF)".

-As an inclusion position for the included file, use the file location of the file where it
was included but *after* the macro expansions. We want the macro expansions to be considered
as before-in-translation-unit for everything in the included file.

-In the preprocessing record take into account that only inclusion directives can be encountered
as "out-of-order" (by comparing the start of the range which for inclusions is the hash location)
and use binary search if there is an extreme number of macro expansions in the include directive.
