    testsuite: aarch64: Fix failing vector structure tests on big-endian
    
    Recent refactoring of the arm_neon.h header enabled better code
    generation for intrinsics that manipulate vector structures. New
    tests were also added to verify the benefit of these changes. It now
    transpires that the code generation improvements are observed only on
    little-endian systems. This patch restricts the code generation tests
    to little-endian targets.
