    aarch64, testsuite: Prevent stp in lr_free_1.c
    
    The test is looking for individual stores which are able to be merged
    into stp instructions.  The test currently passes -fno-schedule-fusion
    -fno-peephole2, presumably to prevent these stores from being turned
    into stps, but this is no longer sufficient with the new ldp/stp fusion
    pass.
    
    As such, we add --param=aarch64-stp-policy=never to prevent stps being
    formed.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.target/aarch64/lr_free_1.c: Add
            --param=aarch64-stp-policy=never to dg-options.
