The motivation is to mark dump methods as used in debug builds so that they can
be called from lldb, but to not do so in release builds so that they can be
dead-stripped.
There's lots of potential follow-up work suggested in the thread
"Should dump methods be LLVM_ATTRIBUTE_USED only in debug builds?" on cfe-dev,
but everyone seems to agreen on this subset.
Macro name chosen by fair coin toss.

Back out the part of r198399 that enabled LLVM_FINAL/LLVM_OVERRIDE on VS 2010.
DwarfUnit.h legitimately uses them on destructors which unfortunately triggers
Compiler Error C3665 (override specifier not allowed on a destructor/finalizer)
prior to MSVC 2012:
virtual ~DwarfCompileUnit() LLVM_OVERRIDE;

The 'sealed' definition of LLVM_FINAL can be dropped once VS 2010 is
decommissioned.
Some of this is speculative so will keep an eye on the waterfall -- ping me if
you see failures.
Incremental work towards C++11 migration.

This is needed to guard an upcoming feature in clang until the C++11 transition
is complete, at which point it can be removed.

Most people are using MSVC 2012, which lacks the <initializer_list>
header. MSVC 2013 shipped with that header, but it has not yet been
tested. If clang works with the 2013 header, then we can enable this by
checking the value of _MSC_VER.

The underlying type of all plain enums in MSVC is 'int', even if the
enumerator contains large 32-bit unsigned values or values greater than
UINT_MAX. The only way to get a large or unsigned enum type is to
request it explicitly with the C++11 strong enum types feature.
However, since LLVM isn't C++11 yet, I had to add a conditional
LLVM_ENUM_INT_TYPE to Compiler.h to control its usage.
The motivating true positive for this change is compiling PointerIntPair
with MSVC for win64. The PointerIntMask value is supposed to be pointer
sized value of all ones with some low zeros. Instead, it's truncated to
32-bits! We are only saved later because it is sign extended back in
the AND with int64_t, and we happen to want all ones.
This silences lots of -Wmicrosoft warnings during a clang self-host
targeting Windows.

This reverts r185841 and relands r185831 without using
__has_attribute(const).
Clang prior to r161767 (between 3.1 and 3.2) does not accept
__has_attribute(const) due to rdar://10253857. __const and __const__
are both keyword aliases of const, so they don't work either.
I was able to repro the buildbot failure using clang 3.1 and this patch
fixes it. Various important versions of XCode use clang 2.9-ish, so
this workaround is necessary.

When targetting Windows, clang does not define __GNUC__, and as a result
we don't use our attributes with it. This leads to warnings about
unused functions that are already annotated with LLVM_ATTRIBUTE_UNUSED.
Rather than testing for __clang__, we can use its __has_attribute and
__has_builtin macros directlty.
While I'm here, conditionally define and use __GNUC_PREREQ for gcc
version checks. Spelling the check out with three comparisons is
verbose and error prone.

This change lets us bootstrap LLVM/Clang under ASan and MSan. It contains
fixes for 2 issues:
- X86JIT reads return address from stack, which MSan does not know is
initialized.
- bugpoint tests run binaries with RLIMIT_AS. This does not work with certain
Sanitizers.
We are no longer including config.h in Compiler.h with this change.

1) This was the name in the comment block. ;]
2) It matches Clang's __has_feature naming convention.

This expands to '&', and is intended to be used when an /optional/ rvalue
override is available.
Before:
void foo() const { ... }
After:
void foo() const LLVM_LVALUE_FUNCTION { ... }
void foo() && { ... }
This is used to allow moving the contents of an Optional.

Rationale: For each preprocessor macro, either the definedness is what's
meaningful, or the value is what's meaningful, or both. If definedness is
meaningful, we should use #ifdef. If the value is meaningful, we should use
and #ifdef interchangeably for the same macro, seems ugly to me, even if
undefined macros are zero if used.
This also has the benefit that including an LLVM header doesn't prevent
you from compiling with -Wundef -Werror.

Note that support for rvalue references does not imply support
for the full set of move-related STL operations.
I've preserved support for an odd little thing in insert() where
we're trying to support inserting a new element from an existing
one. If we actually want to support that, there's a lot more we
need to do: insert can call either grow or push_back, neither of
which is safe against this particular use pattern.
