[ASTUnit] Don't let the preamble diagnostics out-live the CompilerInstance that created them,
this is inherently unsafe.

Instead get the diagnostic info into a SourceManager-independent form.

Add 'remark' diagnostic type in 'clang'

A 'remark' is information that is not an error or a warning, but rather some
additional information provided to the user. In contrast to a 'note' a 'remark'
is an independent diagnostic, whereas a 'note' always depends on another
diagnostic.

A typical use case for remark nodes is information provided to the user, e.g.
information provided by the vectorizer about loops that have been vectorized.

This patch provides the initial implementation of 'remarks'. It includes the
actual definiton of the remark nodes, their printing as well as basic parameter
handling. We are reusing the existing diagnostic parameters which means a remark
can be enabled with normal '-Wdiagnostic-name' flags and can be upgraded to
an error using '-Werror=diagnostic-name'. '-Werror' alone does not upgrade
remarks.

This patch is by intention minimal in terms of parameter handling. More
experience and more discussions will most likely lead to further enhancements
in the parameter handling.

Don't suggest non-static methods as corrections when they obviously
won't work (i.e. when not doing a member lookup and not in a method from
the same class or a descendant class).

When completing Objective-C instance method invocations, perform a contextual conversion to an Objective-C pointer type of the target expression if needed. This fixes code completion of method invocations where the target is a smart pointer that has an explicit conversion operator to an Objective-C type.

Reapply fixed "Honour 'use-external-names' in FileManager"

Was r202442

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.

Add Clang docs about MSVC compatibility

This documents some of the status of supported functionality in MSVC
quirks mode.  Some of this should be in
http://clang.llvm.org/compatibility.html instead when things have
stabilized.

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).

Fixed an assertion failure related to bitfield lowering.

When lowering a bitfield, CGRecordLowering would assign the wrong 
storage type to a bitfield in some cases and trigger an assertion.  In 
these cases the layout was still correct, just the bitfield info was 
wrong.
