    aarch64, testsuite: Tweak sve/pcs/args_9.c to allow stps
    
    With the new ldp/stp pass enabled, there is a change in the codegen for
    this test as follows:
    
            add     x8, sp, 16
            ptrue   p3.h, mul3
            str     p3, [x8]
    -       str     x8, [sp, 8]
    -       str     x9, [sp]
    +       stp     x9, x8, [sp]
            ptrue   p3.d, vl8
            ptrue   p2.s, vl7
            ptrue   p1.h, vl6
    
    i.e. we now form an stp that we were missing previously. This patch
    adjusts the scan-assembler such that it should pass whether or not
    we form the stp.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.target/aarch64/sve/pcs/args_9.c: Adjust scan-assemblers to
            allow for stp.
