Fix mangling for block literals.
Blocks, like lambdas, can be written in contexts which are required to be
treated as the same under ODR. Unlike lambdas, it isn't possible to actually
take the address of a block, so the mangling of the block itself doesn't
matter. However, objects like static variables inside a block do need to
be mangled in a consistent way.
There are basically three components here. One, block literals need a
consistent numbering. Two, objects/types inside a block literal need
to be mangled using it. Three, objects/types inside a block literal need
to have their linkage computed correctly.

Fix PR16508.
When phis get lowered, destination copies are inserted using an iterator that is
determined once for all phis in the block, which BuildMI interprets as a request
to insert an instruction directly before the iterator. In the case of a cyclic
phi, source copies may also be inserted directly before this iterator, which can
cause source copies to be inserted before destination copies. The fix is to keep
an iterator to the last phi and then advance it while lowering each phi in order
to insert destination copies directly after the phis.

Teach -Wunsequenced that the side-effects of a function evaluation are sequenced
before the value computation of the result. In C, this is implied by there being
a sequence point after their evaluation, and in C++, it's implied by the
side-effects being sequenced before the expressions and statements in the
function body.

Reinstate r185229, reverted in r185256, with a tweak: further ignore the
standard's rule that an extern "C" declaration conflicts with any entity in the
global scope with the same name. Now we only care if the global scope entity is
a variable declaration (and so might have the same mangled name as the extern
"C" declaration). This has been reported as a standard defect.
Original commit message:
PR7927, PR16247: Reimplement handling of matching extern "C" declarations
across scopes.
When we declare an extern "C" name that is not a redeclaration of an entity in
the same scope, check whether it redeclares some extern "C" entity from another
scope, and if not, check whether it conflicts with a (non-extern-"C") entity in
the translation unit.
When we declare a name in the translation unit that is not a redeclaration,
check whether it conflicts with any extern "C" entities (possibly from other
scopes).

Add enumerators to TestVisitor::Language to allow visitor tests to
explicitly specify use of C++98 or C++11. Lang_CXX is preserved as
an alias for Lang_CXX98.
This does not add Lang_CXX1Y or Lang_C11, on the assumption that it's
better to add them if/when they are needed.
(This is a prerequisite for a test in a later patch for RecursiveASTVisitor.)

Matthew Dempsky: POSIX defines that the _POSIX_C_SOURCE macros are to be set by user
code to specify what version of POSIX the system should provide. If
you want to check what version of POSIX is actually available, you're
supposed to test _POSIX_VERSION.
However, since sysconf() has been in POSIX since 1995, it's probably
safe to assume it's available on any system with a C++11 compiler,
especially if _SC_NPROCESSORS_ONLN is defined too. So no point in a
complicated preprocessor rule if just we unconditionally include
<unistd.h> (on non-Windows systems).
Also, I've added a #warning for to help porters detect when a suitable
implementation isn't detected at compile-time.
