Aaron Ballman 50af8d4670 Sometimes report_fatal_error is called when there is not a handler function used to fail gracefully. In that case, RunInterruptHandlers is called, which attempts to enter a critical section object. Ensure that the critical section is properly initialized so that this code functions properly, and tools like clang-tidy do not crash in Debug builds.

Zachary Turner cd132c9b0d Replace PrintStackTrace(FILE*) with PrintStackTrace(raw_ostream&)
This will be followed by a change on the clang side to update
the only user of this function with the new version.

Reid Kleckner e658058cc0 Silence -Wmissing-braces warning from clang-cl
The first element of STACKFRAME64 is a struct and Clang wants us to put
braces around it's initialization. Instead, drop the zero. The result
should be the same.

Zachary Turner 62b7b617a8 [Windows] Implement PrintStackTrace(FILE*)
llvm::sys::PrintBacktrace(FILE*) is supposed to print a backtrace
of the current thread given the current PC.  This function was
unimplemented on Windows, and instead the only time we could
print a backtrace was as the result of an exception through
LLVMUnhandledExceptionFilter.

This patch implements backtracing of self by using
RtlCaptureContext to get a CONTEXT for the current thread, and
moving the printing and StackWalk64 code to a common method that
printing own stack trace and printing stack trace of an exception
can use.

David Majnemer 17a44966be Windows: Be more explicit with Win32 APIs
This addresses several issues in a similar vein:
 - Use the Unicode APIs when possible, running nm on clang shows that we
   only use Unicode APIs except for FormatMessage, CreateSemaphore, and
   GetModuleHandle.  AFAICT, the latter two are coming from MinGW and
   not LLVM itself.
 - Make getMainExecutable more resilient.  It previously considered
   return values of zero from ::GetModuleFileNameA to be acceptable.

David Majnemer 80bea0c315 Windows: Add support for unicode command lines
Summary:
The MSVCRT deliberately sends main() code-page specific characters.
This isn't too useful to LLVM as we end up converting the arguments to
UTF-16 and subsequently attempt to use the result as, for example, a
file name.  Instead, we need to have the ability to access the Unicode
command line and transform it to UTF-8.

This has the distinct advantage over using the MSVC-specific wmain()
function as our entry point because:
 - It doesn't work on cygwin.
 - It only work on MinGW with caveats and only then on certain versions.
 - We get to keep our entry point as main(). :)

N.B.  This patch includes fixes to other parts of lib/Support/Windows
s.t. we would be able to take advantage of getting the Unicode paths.
E.G.  clang spawning clang -cc1 would want to give it Unicode arguments.

Rafael Espindola 05e53fc0c1 Improve our error handling on windows.
* Remove LLVM_ENABLE_CRT_REPORT. LLVM_DISABLE_CRASH_REPORT made it redundant.
* set Return to 1, so that we get a stack trace on failure.
* don't call _exit, so that we get a negative exit value and "not --crash"
  correctly differentiates crashes and regular errors.

This is a bit experimental since the documentation on this interface is sparse.
It doesn't bring up a dialog on my windows setup, but feel free to revert
if it causes problem for your setup (and let me know what it is so that I
can try to fix this patch).

Reid Kleckner bd39f21336 [Support] Disable assertion dialogs from the MSVC debug CRT
Summary:
Sets a report hook that emulates pressing "retry" in the "abort, retry,
ignore" dialog box that _CrtDbgReport normally raises.  There are many
other ways to disable assertion reports, but this was the only way I
could find that still calls our exception handler.

Chandler Carruth ed0881b2a6 Use the new script to sort the includes of every file under lib.
Sooooo many of these had incorrect or strange main module includes.
I have manually inspected all of these, and fixed the main module
include to be the nearest plausible thing I could find. If you own or
care about any of these source files, I encourage you to take some time
and check that these edits were sensible. I can't have broken anything
(I strictly added headers, and reordered them, never removed), but they
may not be the headers you'd really like to identify as containing the
API being implemented.

Many forward declarations and missing includes were added to a header
files to allow them to parse cleanly when included first. The main
module rule does in fact have its merits. =]
