    [AArch64] Track FP registers in prologue analyzer

    We don't track FP registers in aarch64 prologue analyzer, so this causes
    an internal error when FP registers are saved by "stp" instruction in
    prologue (stp       d8, d9, [sp,#128]),

     tbreak _Unwind_RaiseException^M
     aarch64-tdep.c:335: internal-error: CORE_ADDR
aarch64_analyze_prologue(gdbarch*, CORE_ADDR, CORE_ADDR,
aarch64_prologue_cache*): Assertion `inst.operands[0].type == AARCH64_OPND_Rt'
failed.^M
     A problem internal to GDB has been detected,

    This patch teaches GDB to track FP registers (D registers) in prologue
    analyzer.

        * aarch64-tdep.c: Replace 32 with AARCH64_D_REGISTER_COUNT.
        (aarch64_analyze_prologue): Extend array 'regs' for D registers.
        Assert that operand 0 and 1 can be X or D registers.  Update
        register number for D registers.  Update registers in frame
        cache.
        * aarch64-tdep.h (AARCH64_D_REGISTER_COUNT): New macro.
