instruction. The class also consolidates the code for detecting constant
splats that's shared across PowerPC and the CellSPU backends (and might be
useful for other backends.) Also introduces SelectionDAG::getBUID_VECTOR() for
generating new BUILD_VECTOR nodes.

- Implement instance/class overloading in ObjCContainerDecl (removing a FIXME). This involved hacking NamedDecl::declarationReplaces(), which took awhile to figure out (didn't realize replace was the default).
- Changed Sema::ActOnInstanceMessage() to remove redundant warnings when dealing with protocols. For now, I've omitted the "protocol" term in the diagnostic. It simplifies the code flow and wan't always 100% accurate (e.g. "Foo<Prot>" looks in the class interface, not just the protocol).
- Changed several test cases to jive with the above changes.

memcpy to match the alignment of the destination. It isn't necessary
for making loads and stores handled like the SSE loadu/storeu
intrinsics, and it was causing a performance regression in
MultiSource/Applications/JM/lencod.
The problem appears to have been a memcpy that copies from some
highly aligned array into an alloca; the alloca was then being
assigned a large alignment, which required codegen to perform
dynamic stack-pointer re-alignment, which forced the enclosing
function to have a frame pointer, which led to increased spilling.

helper isConstantInitializer) to check whether an initializer is
constant. This passes tests, but it's possible that it'll cause
regressions with real-world code.
Future work:
1. The diagnostics obtained this way are lower quality at the moment;
some work both here and in Evaluate is needed for accurate diagnostics.
2. We probably need some extra code when we're in -pedantic mode so we
can strictly enforce the rules in C99 6.6p7.
3. Dead code cleanup (this should wait until after 2, because we might
want to re-use some of the code).

I know, these follow the exact same rules as pointers, so I just made
them use the same codepath. Someone more familiar with ObjC should
double-check this, though.
