    [arm] avoid aes-1742098 mitigation in combine tests
    
    The expected asm output for aes-fuse-[12].c does not correspond to
    that which is generated when -mfix-cortex-a57-aes-1742098 is enabled.
    The mitigation was introduced after the test, and enabled by default
    for the selected processor, a72.  Select a53 instead, where the
    migitation is not enabled by default, and all the expected fusions can
    take place.
    
    
    for  gcc/testsuite/ChangeLog
    
            * gcc.target/arm/aes-fuse-1.c: Switch to -mcpu=cortex-a53.
            * gcc.target/arm/aes-fuse-2.c: Likewise.
