C++1y: track object lifetime during constexpr evaluation, and don't allow
objects to be used once their lifetimes end. This completes the C++1y
constexpr extensions.

In C++11 mode, when an integral constant expression is desired and we have a
value of class type, look for a unique conversion operator converting to
integral or unscoped enumeration type and use that. Implements [expr.const]p5.
Sema::VerifyIntegerConstantExpression now performs the conversion and returns
the converted result. Some important callers of Expr::isIntegralConstantExpr
have been switched over to using it (including all of those required for C++11
conformance); this switch brings a side-benefit of improved diagnostics and, in
several cases, simpler code. However, some language extensions and attributes
have not been moved across and will not perform implicit conversions on
constant expressions of literal class type where an ICE is required.
In passing, fix static_assert to perform a contextual conversion to bool on its
argument.

Pedantic diagnostic correction: in C++, we have integral constant expressions,
not integer constant expressions. In passing, fix the 'folding is an extension'
diagnostic to not claim we're accepting the code, since that's not true in
-pedantic-errors mode, and add this diagnostic to -Wgnu.

Change the diagnostics which said 'accepted as an extension' to instead say
'is an extension'. The former is inappropriate and confusing when building with
-Werror/-pedantic-errors.

constexpr handling improvements. Produce detailed diagnostics when a 'constexpr'
variable is initialized by a non-constant expression, and pass in the variable
being declared so that earlier-initialized fields' values can be used.
Rearrange VarDecl init evaluation to make this possible, and in so doing fix a
long-standing issue in our C++ constant expression handling, where we would
mishandle cases like:
extern const int a;
const int n = a;
const int a = 5;
int arr[n];
Here, n is not initialized by a constant expression, so can't be used in an ICE,
even though the initialization expression would be an ICE if it appeared later
in the TU. This requires computing whether the initializer is an ICE eagerly,
and saving that information in PCH files.

Constant expression evaluation: evaluate lvalues as lvalues, and rvalues as
rvalues, as C++11 constant evaluation semantics require. DeclRefs referring to
references can now use the normal initialization-caching codepath, which
incidentally fixes a crash in cyclic initialization of references.

In accordance with the C89, C99 and C++98 standards, ICEs can only contain
floating-point literals if they are the immediate operands of casts.
ImplicitCastExpr is not a cast in the language-standards sense.

Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).

static_cast, reinterpret_cast, and const_cast can all be used in C++
integral constant expressions (for conversions to integer types,
naturally). I don't *think* that const_casts will ever get to this
point, but I also can't convince myself that they won't... so I've
taken the safe route and allowed the ICE checking code to look at
const_cast.
