David Blaikie abe1a398e3 Render anonymous entities as '(anonymous <thing>)' (and lambdas as '(lambda at ... )')
For namespaces, this is consistent with mangling and GCC's debug info
behavior. For structs, GCC uses <anonymous struct> but we prefer
consistency between all anonymous entities but don't want to confuse
them with template arguments, etc, so we'll just go with parens in all
cases.

David Blaikie 5ee3d0080a Add the location of Decls to ast dump.
While investigating some debug info issues, Eric and I came across a
particular template case where the location of a decl was quite
different from the range of the same decl. It might've been rather
helpful if the dumper had actually showed us this.

Richard Smith 961eae5f95 Save out a correct lookup table if a lookup table entry is stale (it contains
an out-of-date external decls list). This happens if we declare some names,
force the lookup table for the decl context to be built, import a module that
adds more decls for the name, then write out our module without looking up the
name.

Ben Langmuir c3ea5654f9 Prevent lookup of subframework modules by name without parent framework
We were 'allowing' the following import
@import Sub;

where Sub is a subframework of Foo and we had a -F path inside
Foo.framework/Frameworks and no module map file for Sub. This would
later hit assertion failures in debug builds.

Now we should correctly diagnose this as a module not found error.

Ben Langmuir 984e1df77a Add a new spelling for module map files 'module.modulemap'
This name, while more verbose, plays more nicely with tools that use
file extensions to determine file types. The existing spelling
'module.map' will continue to work, but the new spelling will take
precedence.

In frameworks, this new filename will only go in a new 'Modules'
sub-directory.

Similarly, add a module.private.modulemap corresponding to
module_private.map.

Richard Smith 49f906a36f If a module A exports a macro M, and a module B imports that macro and #undef's
it, importers of B should not see the macro. This is complicated by the fact
that A's macro could also be visible through a different path. The rules (as
hashed out on cfe-commits) are included as a documentation update in this
change.

With this, the number of regressions in libc++'s testsuite when modules are
enabled drops from 47 to 7. Those remaining 7 are also macro-related, and are
due to remaining bugs in this change (in particular, the handling of submodules
is imperfect).

Dmitri Gribenko ea4d1c32fb libclang: report error code for bad PCH files
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.

Ben Langmuir 332aafede3 Fix autolinking when modules are imported in pch files
Add the ImportDecl to the set of interesting delcarations that are
deserialized eagerly when an AST file is loaded (rather than lazily like
most decls). This is required to get auto linking to work when there is
no explicit import in the main file. Also resolve a FIXME to rename
'ExternalDefinitions', since that is only one of the things that need eager
deserialization. The new name is 'EagerlyDeserializedDecls'. The corresponding
AST bitcode is also renamed.

Hans Wennborg c9bd88e681 Remove the -cxx-abi command-line flag.
This makes the C++ ABI depend entirely on the target: MS ABI for -win32 triples,
Itanium otherwise. It's no longer possible to do weird combinations.

To be able to run a test with a specific ABI without constraining it to a
specific triple, new substitutions are added to lit: %itanium_abi_triple and
%ms_abi_triple can be used to get the current target triple adjusted to the
desired ABI. For example, if the test suite is running with the i686-pc-win32
target, %itanium_abi_triple will expand to i686-pc-mingw32.

Daniel Jasper 92669ee45c Enable layering check in unavailable modules.
If a header file belonging to a certain module is not found on the
filesystem, that header gets marked as unavailable. Now, the layering
warning (-fmodules-decluse) should still warn about headers of this
module being wrongfully included. Currently, headers belonging to those
modules are just treated as not belonging to modules at all which means
they can be included freely from everywhere.

To implement this (somewhat) cleanly, I have moved most of the layering
checks into the ModuleMap. This will also help with showing FixIts
later.

Daniel Jasper 0761a8a085 Modules: Don't warn upon missing headers while reading the module map.
Instead, mark the module as unavailable so that clang errors as soon as
someone tries to build this module.

This works towards the long-term goal of not stat'ing the header files at all
while reading the module map and instead read them only when the module is
being built (there is a corresponding FIXME in parseHeaderDecl()).  However, it
seems non-trivial to get there and this unblock us and moves us into the right
direction.

Also changed the implementation to reuse the same DiagnosticsEngine.
