00a2d1554b Naturally align doubles in the constant pool, set PrivateGlobalPrefix on 
darwin, use it when printing the constant pool indices so the labels are
appropriately private, emit cp entries to .const instead of .data on darwin
and only emit a single .section for the constant pool, not one for each
entry.

7d513f65ae Teach LLVM how to scalarize packed types. Currently, this only works on 
packed types with an element count of 1, although more generic support is
coming.  This allows LLVM to turn the following code:

void %foo(<1 x float> * %a) {
entry:
  %tmp1 = load <1 x float> * %a;
  %tmp2 = add <1 x float> %tmp1, %tmp1
  store <1 x float> %tmp2, <1 x float> *%a
  ret void
}

Into:

_foo:
        lfs f0, 0(r3)
        fadds f0, f0, f0
        stfs f0, 0(r3)
        blr

fc4928a31a Implement a refinement to the mem2reg algorithm for cases where an alloca 
has a single def.  In this case, look for uses that are dominated by the def
and attempt to rewrite them to directly use the stored value.

This speeds up mem2reg on these values and reduces the number of phi nodes
inserted.  This should address PR665.

b6af6ea0d4 add an option to generate completely non-pic code, corresponding to what 
gcc -static produces on PPC.  This is used for building kexts and other things.

With this, materializing the address of a global looks like:

        lis r2, ha16(L_H$non_lazy_ptr)
        la r3, lo16(L_H$non_lazy_ptr)(r2)

we're still emitting stubs for functions, which is wrong.  That is next.

4581404290 Enable global address legalization, fixing a todo and allowing the removal 
of some code.  This exposes the implicit load from the stubs to the DAG, allowing
them to be optimized by the dag combiner.  It also moves darwin specific stuff
out of the isel into the legalizer, and allows more to be moved to the .td file.

8d04987a39 Add an initial hack at legalizing GlobalAddress into the appropriate nodes 
on Darwin to remove smarts from the isel.  This is currently disabled by
default (uncomment setOperationAction(ISD::GlobalAddress to enable it).
tblgen needs to become smarter about tglobaladdr nodes and bigger patterns
needed to be added to the .td file.  However, we can currently emit stuff like
this:  :)

        li r2, lo16(L_x$non_lazy_ptr)
        lis r3, ha16(L_x$non_lazy_ptr)
        lwzx r2, r3, r2

The obvious improvements will follow.
