Sean Silva 2103c38a99 [cleanup] Factor out some checks. NFC.
The core logic in main() is actually pretty simple, but there's lots of
stuff that has been added over time which obscures the flow of the code.
In upcoming patches, I'll be pulling more stuff out of the main
codepath.

I'm open to naming suggestions for these helper functions.

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 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.

Alp Toker 1761f11801 Eliminate DefaultImageName from the Driver constructor
All callers were passing in "a.out" or garbage so a sensible default works fine
here as a cleanup.

This also brings about the possibility of adapting the value based on the
driver's compatibility mode in future.

The setting can still be changed via Driver::DefaultImageName as needed.

Bob Wilson 39265b96b5 Remove support for the QA_OVERRIDE_GCC3_OPTIONS environment variable.
In r199283 I switched the name of this variable to CCC_OVERRIDE_OPTIONS, but
I kept some code to continue recognizing the old name temporarily. As far as
I know, the only use of this was for some internal testing at Apple, and we've
now switched to use the new name. If anyone else is still using this and needs
more time to switch names, I guess we'll find out! <rdar://problem/15821425>

Chandler Carruth 5553d0d4ca Sort all the #include lines with LLVM's utils/sort_includes.py which

David Majnemer 3f8f8c9dbd Driver: Use the canonical command line arguments.
Summary:
Use the arguments given to the OS at process creation-time instead of
the arguments passed into main() by the C runtime environment.  The ones
that main() received may not be suitable (e.g. not Unicode).

Depends on D1834

Hans Wennborg 70850d83dc Turn Driver::CCCIsCXX and CCCIsCPP into a single Mode enum,
and add a new option --driver-mode= to control it explicitly.

The CCCIsCXX and CCCIsCPP flags were non-overlapping, i.e. there
are currently really three modes that Clang can run in: gcc, g++
or cpp, so it makes sense to represent them as an enum.

Having a command line flag to control it helps testing.

Reid Kleckner 61b23b7edc [Driver] Use LLVM's response file parser because it can read UTF-16
MSBuild writes response files as UTF-16 little endian with a byte order
mark.  With this change, clang will be able to read them, although we
still can't parse any of their flags.

Adds a UTF-16-LE response file with a BOM for testing.

Reid Kleckner 898229ab4b [Driver] Refactor clang driver to use LLVM's Option library
The big changes are:
- Deleting Driver/(Arg|Opt)*
- Rewriting includes to llvm/Option/ and re-sorting
- 'using namespace llvm::opt' in clang::driver
- Fixing the autoconf build by adding option everywhere

As discussed in the review, this change includes using directives in
header files.  I'll make follow up changes to remove those in favor of
name specifiers.
