libclang exposes the type of 'int (Foo);' (a global variable of type int
called Foo) as CXType_Unexposed. This is because Clang represents Foo's
type as ParenType{BuiltinType{Int}}, and libclang does not handle
ParenType.
Make libclang return CXType_Int as the type of 'int (Foo);' by
unwrapping ParenType transparently.

SPIR-V encodes the read_only and write_only access qualifiers of pipes,
so separate LLVM IR types are required to target SPIR-V. Other backends
may also find this useful.
These new types are `opencl.pipe_ro_t` and `opencl.pipe_wo_t`, which
replace `opencl.pipe_t`.
This replaces __get_pipe_num_packets(...) and __get_pipe_max_packets(...)
which took a read_only pipe with separate versions for read_only and
write_only pipes, namely:
* __get_pipe_num_packets_ro(...)
* __get_pipe_num_packets_wo(...)
* __get_pipe_max_packets_ro(...)
* __get_pipe_max_packets_wo(...)
These separate versions exist to avoid needing a bitcast to one of the
two qualified pipe types.

Summary:
Make completion behave consistently no matter if it is run at the
start, in the middle or at the end of an identifier that happens to
be a keyword or a macro name. Since completion is often ran on
incomplete identifiers, they may turn into keywords by accident.
For example, we should produce same results for all of these
completion points:
// ^ is completion point.
^class
cla^ss
class^
Previously clang produced different results for the last case (as if
the completion point was after a space: `class ^`).
This change also updates some offsets in tests that (unintentionally?)
relied on the old behavior.

All attributes have a source range associated with it. However, implicit
attributes are added by the compiler, and not added because the user
wrote something in the input. So no token type should be set to
CXCursor_*Attr.
The problem was visible when a class gets marked by e.g.
MSInheritanceAttr, which has the full CXXRecordDecl's range as its
own range. The effect of marking that range as CXCursor_UnexposedAttr
was that all cursors for the record decl, including all child decls,
would become CXCursor_UnexposedAttr.

Summary:
It should be safe, since other code paths are already generating
implicit members even in invalid CXXRecordDecls (e.g. lookup).
If we don't generate implicit members on CXXRecordDecl's completion,
they will be generated by next lookup of constructors. This causes a
crash when the following conditions are met:
- a CXXRecordDecl is invalid,
- it is provided via ExternalASTSource (e.g. from PCH),
- it has inherited constructors (they create ShadowDecls),
- lookup of its constructors was not run before ASTWriter serialized
it.
This may require the ShadowDecls created for inherited constructors to
be removed from the class, but that's no longer possible since class is
provided by ExternalASTSource.
See provided lit test for an example.

it's not a very useful default, so we populate it by default.
While here:
- remove an unused test file accidentally added in r322371.

Instead a hash is stored with a record invocation. When a reproducer is

Adjusted PrintingPolicy inside code completion to avoid printing some

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 {

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.

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.

The new behavior includes the '#' from the opening directive and the full text

before - "int i", after - "int i = 10"

Summary:
This patch prevents getCanonicalDecl returning nullptr in case it finds
a canonical TemplateDeclaration with no attached TemplatedDecl.
Found by running the indexer over a version of the standard library deep inside
a template metaprogramming mess.

Unless it's one of the special cases (tag, category) that we can handle.
This syncs up the check between handling a decl and handling a relation.
This would cause invalid nameless decls to end up in relations despite
having no name or USR.

the serialised diagnostics
Clang should avoid calling report_fatal_error when the file with the serialised
diagnostics is empty. This commit changes Clang's serialised diagnostic reader,
now it reports an appropriate error instead of crashing.

In C mode clang fails to merge the textually included definition with the one imported from a module. The C lookup rules fail to find the imported definition because its linkage is internal in non C++ mode.
This patch reinstates some of the ODR merging rules for typedefs of anonymous tags for languages other than C++.
Patch by Raphael Isemann and me (D34510).

Redeclaration lookup should never find hidden enumerators in C, because
they do not have linkage (C11 6.2.2/6)
The linkage of an enumerator should be VisibleNoLinkage, and
isHiddenDeclarationVisible should be checking hasExternalFormalLinkage.
This is was reviewed as part of D31778, but splitted into a different
commit for clarity.

dependent initializer
This commit fixes incorrect source positions of dependent c'tor initializers
like in the following code:
template<typename MyBase>
struct Derived: MyBase::InnerIterator
{
Derived() : MyBase::InnerIterator() {} /// This line is problematic: all positions point to InnerIterator and nothing points to MyBase
};

of class template specializations
This commit fixes an issue where a forward declaration of a class template
specialization was not related to the base template. We need to relate even
forward declarations because specializations don't have to be defined.

'HandleEndifDirective' asserts that 'WasSkipping' is false, so switch to using 'FoundNonSkip' as the hint for 'SingleFileParseMode' to keep going with parsing.

"specializationOf" relation if they pseudo-override a type in the base template
This commit fixes an issue where Xcode's renaming engine couldn't find the
reference to the second occurrence of "InnerClass" in this example:
template<typename T> struct Ts { template<typename U> struct InnerClass { }; };
template<> struct Ts<int> {
template<typename U> struct InnerClass; // This occurrence wasn't renamed
};
