5fec5b0495 Add basic support for C++ name mangling according to the Itanium C++ 
ABI to the CodeGen library. Since C++ code-generation is so
incomplete, we can't exercise much of this mangling code. However, a
few smoke tests show that it's doing the same thing as GCC. When C++
codegen matures, we'll extend the ABI tester to verify name-mangling
as well, and complete the implementation here.

At this point, the major client of name mangling is in the uses of the
new "overloadable" attribute in C, which allows overloading. Any
"overloadable" function in C (or in an extern "C" block in C++) will
be mangled the same way that the corresponding C++ function would be
mangled.

d42a0fb41b Upgrade the "excess elements in array initializer" warning to an 
error, since both C99 and C++ consider it an error. For reference, GCC
makes this a warning while G++ makes it an error.

0202cb406e Introduce a new expression node, ImplicitValueInitExpr, that 
represents an implicit value-initialization of a subobject of a
particular type. This replaces the (ab)use of CXXZeroValueInitExpr
within initializer lists for the "holes" that occur due to the use of
C99 designated initializers.

The new test case is currently XFAIL'd, because CodeGen's
ConstExprEmitter (in lib/CodeGen/CGExprConstant.cpp) needs to be
taught to value-initialize when it sees ImplicitValueInitExprs.

56493b0d54 Allow creation of "dummy" compile units for debug information. 
- Although gross, this is needed currently to ensure that we produce
   well formed debug information (to match pace with the assertions
   being added to DebugInfo in LLVM).

When emitting the static variables we need to make sure that the order is preserved. 
Fix this by making StaticDecls a std::list which has O(1) random removal.

f4084708cd Make VLAs usable, and make basic usage work correctly. Also, add a 
simple test that actually does VLA codegen.

Note that despite the fact that the alloca isn't in the entry block, it 
should dominate all uses; this is guaranteed by the restrictions on goto 
into VLA scope in C99.
