Add support for the v1i64 type. This makes better code for this:
...
#include <mmintrin.h>
extern __m64 C;
void baz(__v2si *A, __v2si *B)
{
*A = C;
_mm_empty();
}
We get this:
_baz:
call "L1$pb"
"L1$pb":
popl %eax
movl L_C$non_lazy_ptr-"L1$pb"(%eax), %eax
movq (%eax), %mm0
movl 4(%esp), %eax
movq %mm0, (%eax)
emms
ret
GCC gives us this:
_baz:
pushl %ebx
call L3
"L00000000001$pb":
L3:
popl %ebx
subl $8, %esp
movl L_C$non_lazy_ptr-"L00000000001$pb"(%ebx), %eax
movl (%eax), %edx
movl 4(%eax), %ecx
movl 16(%esp), %eax
movl %edx, (%eax)
movl %ecx, 4(%eax)

Remove a use of getLowBitsSet that caused the mask used for replacement of

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.
