This is a necessary prerequisite for debugging with modules.
The .pcm files become containers that hold the serialized AST which allows
us to store debug information in the module file that can be shared by all
object files that were built importing the module.
This reapplies r230044 with a fixed configure+make build and updated
dependencies and testcase requirements. Over the last iteration this
version adds
- missing target requirements for testcases that specify an x86 triple,
- a missing clangCodeGen.a dependency to libClang.a in the make build.

The code building the code completion string for overloads was providing
less detail compared to the one building completion strings for function
declarations. There was no information about optionals and no information
about what's a parameter and what's a function identifier, everything
besides ResultType, CurrentParameter and special characters was classified
as Text.
This makes code completion strings for overload candidates to follow a
pattern very similar, but not identical, to the one in use for function
declarations:
- return type chunk: ResultType
- function identifier chunk: Text
- parameter chunks: Placeholder
- optional parameter chunks: Optional
- current parameter chunk: CurrentParameter
llvm-svn: 227309
The improved completion in call context now works with:
- Functions.
- Member functions.
- Constructors.
- New expressions.
- Function call expressions.
- Template variants of the previous.
There are still rough edges to be fixed:
- Provide support for optional parameters. (fix known)
- Provide support for member initializers. (fix known)
- Provide support for variadic template functions. (fix unknown)
- Others?

The size of the ID field in CommandInfo was narrow, leading to potential
wrap-around of command IDs, causing misinterpretation later on.
The patch does the following:
- It extends the ID bitfield from 8 to 20 bits.
- It provides a DRY definition of the number of bits for the field to
avoid using literal numbers in different files.
- It introduces a new assertion that checks for the wrap-around.
- It adds the testcase from PR21254.

In code-completion, don't assume there is a MacroInfo for everything,

Predefined decls like 'Protocol' in objc are not loaded from AST files,
so we cannot rely on loading the canonical decl to complete the redecl
chain for redeclarations of these decls. The broken redecl chain was
non-circular, so looping over redecls() would hang.

Since the community says that a blacklist is not good enough, and I don't have

Attribute filtering is currently based on a blacklist, which right now includes

To differentiate between two modules with the same name, we will
consider the path the module map file that they are defined by* part of
the ‘key’ for looking up the precompiled module (pcm file).
Specifically, this patch renames the precompiled module (pcm) files from
cache-path/<module hash>/Foo.pcm
to
cache-path/<module hash>/Foo-<hash of module map path>.pcm
In addition, I’ve taught the ASTReader to re-resolve the names of
imported modules during module loading so that if the header search
context changes between when a module was originally built and when it
is loaded we can rebuild it if necessary. For example, if module A
imports module B
first time:
clang -I /path/to/A -I /path/to/B ...
second time:
clang -I /path/to/A -I /different/path/to/B ...
will now rebuild A as expected.
* in the case of inferred modules, we use the module map file that
allowed the inference, not the __inferred_module.map file, since the
inferred file path is the same for every inferred module.

The idea is to give visibility to more type kinds, especially for getting

This commit improves libclang to report the error condition when
CXTranslationUnit can not be created because of a stale PCH file. This allows
the caller, for example, to rebuild the PCH file and retry the request.
There two are APIs in libclang that return a CXTranslationUnit and don't
support reporting detailed errors (the only error condition is a NULL result).
For these APIs, a second, superior, version is introduced --
clang_createTranslationUnit2 and clang_parseTranslationUnit2. These functions
return a CXTranslationUnit indirectly and also return an error code. Old
functions are still supported and are nothing more than convenience wrappers
that ignore extended error codes.
As a cleanup, this commit also categorizes some libclang errors in the
functions I had to modify anyway.

The purpose of this is to allow (for instance) the module map for /usr/include
to exclude <tgmath.h> and <complex.h> when building in C++ (these headers are
instead provided by the C++ standard library in this case, and the glibc C
<tgmath.h> header would otherwise try to include <complex.h>, resulting in a
module cycle).

variable from being the function to being the enclosing namespace scope (in
C++) or the TU (in C). This allows us to fix a selection of related issues
where we would build incorrect redeclaration chains for such declarations, and
fail to notice type mismatches.
Such declarations are put into a new IdentifierNamespace, IDNS_LocalExtern,
which is only found when searching scopes, and not found when searching
DeclContexts. Such a declaration is only made visible in its DeclContext if
there are no non-LocalExtern declarations.

Move C++-specific tests that were checking if we attach a base class comment to

The problem was that an enum without closing semicolon could be associated as a forward enum
in an erroneous declaration, leading to the identifier being associated with the enum decl but
without a declaration actually referencing it.
This resulted in not having it serialized before serializing the identifier that is associated with.
Also prevent the ASTUnit from querying the serialized DeclID for an invalid top-level decl; it may not
have been serialized.

This helps preserve the type-as-written in the AST, which we need for

+ QualType ArgTy = Param->getTypeSourceInfo()->getType();
... followed by the adjustment in ActOnFunctionDeclarator().

When we are consuming the current token just to enter a new token stream, we push
the current token in the back of the stream so that we get it again.
Unfortunately this had the effect where if the current token is a code-completion one,
we would code-complete once during consuming it and another time after the stream ended.
Fix this by making sure that, in this case, ConsumeAnyToken() will consume a code-completion
token without invoking code-completion.

We now only put empty blocks into a single line, if all of:
- all tokens of the structural element fit into a single line
- we're not in a control flow statement
Note that we usually don't put record definitions into a single line, as
there's usually at least one more token (the semicolon) after the
closing brace. This doesn't hold when we are in a context where there is
no semicolon, like "enum E {}".
There were some missing tests around joining lines around the corner
cases of the allowed number of columns, so this patch adds some.
