    Implement SystemTap SDT probe support for AArch64
    
    This commit implements the needed bits for SystemTap SDT probe support
    on AArch64 architectures.
    
    First, I started by looking at AArch64 assembly specification and
    filling the necessary options on gdbarch's stap machinery in order to
    make the generic asm parser (implemented in stap-probe.c) recognize
    AArch64's asm.
    
    After my last patch for the SystemTap SDT API, which extends it in order
    to accept multiple prefixes and suffixes, this patch became simpler.  I
    also followed Marcus suggestion and did not shared code between 32- and
    64-bit ARM.
    
    Tom asked me in a previous message how I did my tests.  I believe I
    replied that, but just in case: I ran the tests on
    gdb.base/stap-probe.exp by hand.  I also managed to run the tests on
    real hardware, and they pass without regressions.
