ARM: fix ldrexd/strexd
Correct ldrexd and strexd code to always read and write the high word of the 64-bit value from addr+4. Also make ldrexd and strexd agree that for a 64 bit value the address in env->exclusive_addr is that of the low word. This fixes the issues reported in https://bugs.launchpad.net/qemu/+bug/670883 Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Nathan Froyd <froydnj@codesourcery.com>
