[PATCH, AArch64] Enable shuffle on big-endian and turn on the testsuite

[Alan Lawrence]

As a followup to http://gcc.gnu.org/ml/gcc-patches/2014-04/msg00079.html, which 
implements the shuffle operation but still leaves that unused - if/once that's 
gone in, I see no reason now we can't start using it, and enable the appropriate 
tests. I see the following test changes:

Ok for stage 1 (repeat, only after
