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.

Introduce a new expression node, ImplicitValueInitExpr, that

represents an implicit value-initialization of a subobject of a

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.

In incompatible pointer-typed ?: expressions, add implicit conversion
...
of RHSs to id type instead of void* if either has Objective-C object
type.
- This ensures the result can still be used in normal places an
object can be used, like a message send.
Add implicit conversions for ?: applied to qualified id types to
ensure that the RHSs are compatible.
- This prevents a codegen crash (creating invalid PHI nodes).
- Again, this relates to the fact that qualified id types have no
canonical types.
- Note that the implicit type casted to is incorrect, however this
doesn't currently cause problems because of the flexibility of the
id type.

Fix bitfield accesses which straddle the boundary of the underlying

type.
- This generates somewhat less optimal code than before but this is
not hard to rectify once stable (at the cost of slightly more
complex code).
- This currently always uses little-endian ordering of the bitfield.
- This breaks the CodeGen/bitfield.c test because it was grepping for
hard-coded assembly instructions. Will fix once a better test case
is constructed (hard to do without execution).
- This fixes SingleSource/UnitTests/2006-01-23-InitializedBitField.c

Add code to make test/CodeGen/struct-init.c work correctly without the

The reason the pointer cast hack is relevant here is that it makes Sema

The reason for this patch is that I plan to remove the pointer cast hack
sometime soon because it causes strange issues, especially in its

Fix support for _Bool bitfields. The issue is that the bitfield width

Fix several bugs in array -> pointer decomposition.
...
First, we got several CVR propagation cases wrong, which Eli pointed
out in PR2039.
Second, we didn't propagate address space qualifiers correctly, leading
to incorrect lowering of code in CodeGen/address-space.c.
Third, we didn't uniformly propagate the specifier in the array to the
pointer ("int[restrict 4]" -> "int *restrict").
This adds an ASTContext::getArrayDecayedType member that handles the
non-trivial logic for this seemingly simple operation.
