Alp Toker 61dad75b10 cc1as: consolidate option flags with cc1 and eliminate duplication
The clang -cc1as options are nearly a strict subset of -cc1. Instead of
duplicating the definitions and documentation, let's go ahead and share the
definitions in a similar way the current handling of combined driver and
frontend flags, eliminating some of the vestigial legacy surrounding the
assembler subcommand.

Alp Toker 5c53298c1e libclang: pass return code out argument by reference
r212427 formalized the message-passing pattern by making these argument
structures const. This commit changes output arguments to get passed by
reference so we can eliminate mutable fields.

Reid Kleckner 3b5c639f48 Driver: Produce crash diagnostics more often on Windows
Assertion failures call abort(), which return an exit code of 3 on
Windows.  The 'not' utility has the same check.

Unfortunately, the crash-report.c test requires a shell, so it does not
run for me locally, so I can only test this manually.

There's still more work to be done here: we should generate a batch
script instead of a shell script on Windows.

Alp Toker 1a86ad21d1 libclang: make darwin pthread hacks conditional on LLVM_ENABLE_THREADS
Although these aren't strictly related to LLVM's core threading, it's

David Blaikie 66cc07b4f7 Remove 'const' from MemoryBuffers used through the SourceManager
This removes a const_cast added in r211884 that occurred due to an
inconsistency in how MemoryBuffers are handled between some parts of
clang and LLVM.

MemoryBuffers are immutable and the general convention in the LLVM
project is to omit const from immutable types as it's simply
redundant/verbose (see llvm::Type, for example). While this change
doesn't remove "const" from /every/ MemoryBuffer, it at least makes this
chain of ownership/usage consistent.

Chandler Carruth 6666074876 Fix a bug in my previous patch by restoring the behavior that the fatal
error handler is only registered once.

To avoid the use of std::call_once (the obvious way to do this) I've
wrapped everything up into a managed static and done the work in
a constructor. Silly, but it should be effective.

Some out-of-tree libclang users reported this to me, and I've asked them
to put together a test case which exhibits this behavior, but I wanted
to fix things ASAP since the nature of the fix is straight forward.

Chandler Carruth 37ad2582d6 This fixes libclang to cope with the now compile-time multithreaded
selection re-enabled in r211900 in LLVM.

The approach (unlike r211121) doesn't rely on std::mutex or
std::call_once to avoid breaknig cygwin bots.

Alp Toker 541d5070bf Avoid dubious IdentifierInfo::getNameStart() uses
These cases in particular were incurring an extra strlen() when we already knew
the length. They appear to be leftovers from when the interfaces worked with C
strings that have continued to compile due to the implicit StringRef ctor.

Reid Kleckner e931c06b21 Flush C stdio streams upon process termination
Due to what can only be described as a CRT bug, stdout and amazingly
even stderr are not always flushed upon process termination, especially
when the system is under high threading pressure.  I have found two
repros for this:

1) In lib\Support\Threading.cpp, change sys::Mutex to an
std::recursive_mutex and run check-clang.  Usually between 30 and 40
tests will fail.

2) Add OutputDebugStrings in code that runs during static initialization
and static shutdown.  This will sometimes generate similar failures.

After a substantial amount of troubleshooting and debugging, I found
that I could reproduce this from the command line without running
check-clang.  Simply make the mutex change described in #1, then
manually run the following command many times by running it once, then
pressing Up -> Enter very quickly:

D:\src\llvm\build\vs2013\Debug\bin\c-index-test.EXE -cursor-at=D:\src\llvm\tools\clang\test\Index\targeted-preamble.h:2:15 D:\src\llvm\tools\clang\test\Index\targeted-cursor.c -include D:\src\llvm\build\vs2013\tools\clang\test\Index\Output\targeted-cursor.c.tmp.h -Xclang -error-on-deserialized-decl=NestedVar1      -Xclang -error-on-deserialized-decl=TopVar    | D:\src\llvm\build\vs2013\Debug\bin\FileCheck.EXE D:\src\llvm\tools\clang\test\Index\targeted-cursor.c -check-prefix=PREAMBLE-CURSOR1

Sporadically they will fail, and attaching a debugger to a failed
instance indicates that stdin of FileCheck.exe is empty.

Note that due to the repro in #2, we can rule out a bug in the STL's
mutex implementation, and instead conclude that this is a real flake in
the windows test harness.

Test Plan:
Without patch: Ran check-clang 10 times and saw over 30 Unexpected failures on every run.
With patch: Ran check-clang 10 times and saw 0 unexpected failures across all runs.

Alp Toker 1d257e1d0a Remove the last remaining llvm/Config/config.h includes
This corrects long-standing misuses of LLVM's internal config.h.

In most cases the public llvm-config.h header was intended and we can now
remove the old hacks thanks to LLVM r210144.

The config.h header is private, won't be installed and should no longer be
included by clang or other modules.
