    aarch64, testsuite: Fix up pr71727.c
    
    The test is trying to check that we don't use q-register stores with
    -mstrict-align, so actually check specifically for that.
    
    This is a prerequisite to avoid regressing:
    
    scan-assembler-not "add\tx0, x0, :"
    
    with the upcoming ldp fusion pass, as we change where the ldps are
    formed such that a register is used rather than a symbolic (lo_sum)
    address for the first load.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.target/aarch64/pr71727.c: Adjust scan-assembler-not to
            make sure we don't have q-register stores with -mstrict-align.
