  target-arm: Fix A64 Neon MLS

The order of operands for the accumulate step in disas_simd_3same_int()
was reversed. This only affected the MLS instruction, since all the
other accumulating instructions in this category perform an addition
rather than a subtraction.

  target-arm: Load ELF images with the correct machine type for CPU

When trying to load an ELF file specified via -kernel, we need to
pass load_elf() the ELF machine type corresponding to the CPU we're
booting with, not the one corresponding to the softmmu binary
we happen to be running. (The two are different in the case of
loading a 32-bit ARM ELF file into a 32 bit CPU being emulated
by qemu-system aarch64.) This was causing us to incorrectly fail
to load ELF images in this situation.
