This fixes PR9910

__has_extension is a function-like macro which takes the same set
of feature identifiers as __has_feature.  It evaluates to 1 if the
feature is supported by Clang in the current language (either as a
language extension or a standard language feature) or 0 if not.

At the same time, add support for the C1X feature identifiers
c_generic_selections (renamed from generic_selections) and
c_static_assert, and document them.

Patch by myself and Jean-Daniel Dupas.

This introduces a generic base class for the expression evaluator
classes, which handles a few common expression types which were
previously handled separately in each class.  Also, the expression
evaluator now uses ConstStmtVisitor.

llvm-svn: 131281

ConstStmtVisitor is a constness-preserving variant of StmtVisitor.
ConstStmtVisitor and StmtVisitor share an implementation using a common
base class, StmtVisitorBase, which uses a template template parameter
to build pointer types.

constant, also consider whether it's a class type that has any mutable

They are actually grammatically considered definitions and parsed
accordingly.

This fixes the outstanding bugs regarding defaulting functions after
their declarations.

We now really nicely diagnose the following construct (try it!)

int foo() = delete, bar;

Still todo: Defaulted functions other than default constructors
            Test cases (including for the above construct)

llvm-svn: 131228

defaulted default constructors.

As it happens, making sure that we handle out-of-line defaulted
functions properly will involved making sure that we actually parse them
correctly, so that's coming after.

llvm-svn: 131224

We still don't parse out-of-line defaults correctly, which is needed to
get the full effect out of this patch.
