    Support _Complex in hard-VFP abi
    
    Hi,
    When we pass "-mfloat-abi=hard" flag in the GDB testing, we see the
    following fails,
    
    FAIL: gdb.base/callfuncs.exp: p t_float_complex_values(fc1, fc2)
    FAIL: gdb.base/callfuncs.exp: p t_float_complex_many_args(fc1, fc2, fc3, fc4, fc1, fc2, fc3, fc4, fc1, fc2, fc3, fc4, fc1, fc2, fc3, fc4)
    FAIL: gdb.base/callfuncs.exp: p t_double_complex_values(dc1, dc2)
    FAIL: gdb.base/callfuncs.exp: p t_double_complex_many_args(dc1, dc2, dc3, dc4, dc1, dc2, dc3, dc4, dc1, dc2, dc3, dc4, dc1, dc2, dc3, dc4)
    FAIL: gdb.base/callfuncs.exp: p t_long_double_complex_values(ldc1, ldc2)
    FAIL: gdb.base/callfuncs.exp: p t_long_double_complex_many_args(ldc1, ldc2, ldc3, ldc4, ldc1, ldc2, ldc3, ldc4, ldc1, ldc2, ldc3, ldc4, ldc1, ldc2, ldc3, ldc4)
    FAIL: gdb.base/callfuncs.exp: call inferior func with struct - returns float _Complex
    FAIL: gdb.base/callfuncs.exp: call inferior func with struct - returns double _Complex
    
    The hard-VFP ABI was supported by GDB overal, done by this patch
    https://sourceware.org/ml/gdb-patches/2009-07/msg00686.html but
    "vectors and complex types are not currently supported", mentioned in
    the patch.  As a result, these tests fail.
    
    This patch is to support _Complex types in hard-VFP abi.  As specified
    in "7.1.1, Procedure Call Standard for the ARM Arch", the layout of
    _Complex types is a struct, which is identical to the layout on amd64,
    so I copy Mark's comments to amd64 support.
    
    Regression tested on arm-none-eabi target.  OK to apply?

    	* arm-tdep.c (arm_vfp_cprc_sub_candidate): Handle _Complex
    	types.
