Ivan Donchevskii 08ff91089c [libclang] Support querying whether a declaration is invalid
This is useful for e.g. highlighting purposes in an IDE.

Note: First version of this patch was reverted due to failing tests in
opencl-types.cl with -target ppc64le-unknown-linux. These tests are
adapted now.

Ivan Donchevskii 1d18713486 [libclang] Fix cursors for functions with trailing return type
This one was rolled back as follow-up to the failing commit.
Second try.

For the function declaration

auto foo5(Foo) -> Foo;
the parameter tokens were mapped to cursors representing the
FunctionDecl:

Keyword: "auto" [1:1 - 1:5] FunctionDecl=test5:1:6
Identifier: "test5" [1:6 - 1:11] FunctionDecl=test5:1:6
Punctuation: "(" [1:11 - 1:12] FunctionDecl=test5:1:6
Identifier: "X" [1:12 - 1:13] FunctionDecl=test5:1:6 // Ops, not a TypeRef
Punctuation: ")" [1:13 - 1:14] FunctionDecl=test5:1:6
Punctuation: "->" [1:15 - 1:17] FunctionDecl=test5:1:6
Identifier: "X" [1:18 - 1:19] TypeRef=struct X:7:8
Punctuation: ";" [1:19 - 1:20]

Fix this by ensuring that the trailing return type is not visited as
first.

The preinclude is inhibited with –ffreestanding.

Alex Lorenz 80b55ee62d [libclang] Store unsaved file hashes when recording parsing invocations
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.

Ilya Biryukov b5da91c875 Avoid printing some redundant name qualifiers in completion
Summary:
Adjusted PrintingPolicy inside code completion to avoid printing some
redundant name qualifiers.

Before this change, typedefs that were written unqualified in source
code were printed with qualifiers in completion. For example, in the
following code

    struct foo {
        typedef int type;
        type method();
    };

completion item for `method` had return type of `foo::type`, even
though the original code used `type` without qualifiers.
After this change, the completion item has return type `type`, as
originally written in the source code.

Note that this change does not suppress qualifiers written by the
user. For example, in the following code

    typedef int type;
    struct foo {
        typedef int type;
        ::type method(foo::type);
    };

completion item for `method` has return type of `::type` and
parameter type of `foo::type`, as originally written in the source
code.

Erik Verbruggen 6524c05d2c Do not add a colon chunk to the code completion of class inheritance access modifiers
With enabled CINDEXTEST_CODE_COMPLETE_PATTERNS env option (which enables
IncludeCodePatterns in completion options) code completion after colon
currently suggests access modifiers with 2 completion chunks which is
incorrect.

Example:
class A : <Cursor>B
{
}

Currently we get 'NotImplemented:{TypedText public}{Colon :} (40)'
but the correct line is just 'NotImplemented:{TypedText public} (40)'

The fix introduces more specific scope that occurs between ':' and '{'
It allows us to determine when we don't need to add ':' as a second
chunk to the public/protected/private access modifiers.

Move the logic for determining the `wchar_t` type information into the
driver.  Rather than passing the single bit of information of
`-fshort-wchar` indicate to the frontend the desired type of `wchar_t`
through a new `-cc1` option of `-fwchar-type` and indicate the
signedness through `-f{,no-}signed-wchar`.  This replicates the current
logic which was spread throughout Basic into the
`RenderCharacterOptions`.

Most of the changes to the tests are to ensure that the frontend uses
the correct type.  Add a new test set under `test/Driver/wchar_t.c` to
ensure that we calculate the proper types for the various cases.

Zachary Turner 96b04b68ed [lit] Improve tool substitution in lit.
This addresses two sources of inconsistency in test configuration
files.

1. Substitution boundaries.  Previously you would specify a
   substitution, such as 'lli', and then additionally a set
   of characters that should fail to match before and after
   the tool.  This was used, for example, so that matches that
   are parts of full paths would not be replaced.  But not all
   tools did this, and those that did would often re-invent
   the set of characters themselves, leading to inconsistency.
   Now, every tool substitution defaults to using a sane set
   of reasonable defaults and you have to explicitly opt out
   of it.  This actually fixed a few latent bugs that were
   never being surfaced, but only on accident.

2. There was no standard way for the system to decide how to
   locate a tool.  Sometimes you have an explicit path, sometimes
   we would search for it and build up a path ourselves, and
   sometimes we would build up a full command line.  Furthermore,
   there was no standardized way to handle missing tools.  Do we
   warn, fail, ignore, etc?  All of this is now encapsulated in
   the ToolSubst class.  You either specify an exact command to
   run, or an instance of FindTool('<tool-name>') and everything
   else just works.  Furthermore, you can specify an action to
   take if the tool cannot be resolved.

Vedant Kumar 3919a501f3 [Lexer] Report more precise skipped regions (PR34166)
This patch teaches the preprocessor to report more precise source ranges for
code that is skipped due to conditional directives.

The new behavior includes the '#' from the opening directive and the full text
of the line containing the closing directive in the skipped area. This matches
up clang's behavior (we don't IRGen the code between the closing "endif" and
the end of a line).

This also affects the code coverage implementation. See llvm.org/PR34166 (this
also happens to be rdar://problem/23224058).

The old behavior (report the end of the skipped range as the end
location of the 'endif' token) is preserved for indexing clients.

Ilya Biryukov f315000613 Fixed a crash on replaying Preamble's PP conditional stack.
Summary:
The crash occurs when the first token after a preamble is a macro
expansion.
Fixed by moving replayPreambleConditionalStack from Parser into
Preprocessor. It is now called right after the predefines file is
processed.

Ben Langmuir fd6e39c40b [index] Add indexing for unresolved-using declarations
In dependent contexts we end up referencing these, so make sure they
have USRs, and have their declarations indexed. For the most part they
behave like typedefs, but we also need to worry about having multiple
using declarations with the same "name".
