...
#include <mmintrin.h>
extern __m64 C;
void baz(__v2si *A, __v2si *B)

We get this:

"L1$pb":

movq (%eax), %mm0

movl L_C$non_lazy_ptr-"L00000000001$pb"(%ebx), %eax

More APIntification:
...
* Convert the last use of a uint64_t that should have been an APInt.
* Change ComputeMaskedBits to have a const reference argument for the Mask
so that recursions don't cause unneeded temporaries. This causes temps
to be needed in other places (where the mask has to change) but this
change optimizes for the recursion which is more frequent.
* Remove two instances of &ing a Mask with getAllOnesValue. Its not
needed any more because APInt is accurate in its bit computations.
* Start using the getLowBitsSet and getHighBits set methods on APInt
instead of shifting. This makes it more clear in the code what is
going on.
