Added -lines X:Y option to specify line range to process. This is a more human-friendly alternative to -offset and -length.

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.

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.

These flags control language options and user-visible macros, so it's
important to preserve them when analyzing. Rather than try to keep up
with all the -f flags, we'll pass them all through and then ban the ones
we don't want (like -fsyntax-only).

-Wwrite-strings is really an f-flag in disguise: it implies -fconst-strings.

This is important for preprocessing steps, which may output to stdout.

Also, change ENV accesses using barewords to use string keys instead.

PR16414

llvm-svn: 185555

Previously, the CMake build still tried to link clang against the static
analyzer libraries, even if CLANG_ENABLE_STATIC_ANALYZER was off.
Furthermore, clang-check depends on the analyzer, so it should be disabled
(in both CMake and configure builds).

In theory, clang-check could be made to conditionally include analyzer
support (like clang itself), but for now this at least gets a CMake ALL_BUILD
working.

This fixes llvm.org/PR16514.

Before, the computed byte range would include the trailing newline.
clang-format on the other hand counts whitespace as belonging to the
following token, so that git-clang-format inadvertendly reformats the
first unmodified line as well.

It is not entirely clear whether clang-format's behavior itself should
be modified, but for now this seems to be a safe change.

The build system is currently miss-identifying GNU/kFreeBSD as FreeBSD.
This kind of simplification is sometimes useful, but in general it's not correct. 

As GNU/kFreeBSD is an hybrid system, for kernel-related issues we want to match the
build definitions used for FreeBSD, whereas for userland-related issues we want to
match the definitions used for other systems with Glibc.

The current modification adjusts the build system so that they can be distinguished,
and explicitly adds GNU/kFreeBSD to the build checks in which it belongs.

Fixes bug #16445.

WalkUpFromLambdaExpr, so that the Visit* functions are called
on that AST node.

llvm-svn: 185277

Summary:
Some valid pre-C++11 constructs change meaning when lexed in C++11
mode, e.g.
#define x(_a) printf("foo"_a);
(example from http://llvm.org/bugs/show_bug.cgi?id=16342). "foo"_a is treated as
a user-defined string literal when parsed in C++11 mode.
In order to deal with this correctly, we need to set lexing mode according to
which standard the code conforms to. We already have a configuration value for
this (FormatStyle.Standard), which seems to be appropriate to use in this case
as well.

The goal of this sugar node is to be able to look at an arbitrary
FunctionType and tell if any of the parameters were decayed from an
array or function type.  Ultimately this is necessary to implement
Microsoft's C++ name mangling scheme, which mangles decayed arrays
differently from normal pointers.

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.
