Log:
[RS6000] complex long double ABI_V4 fix

Revision 235794 regressed compat/scalar-by-value-6 for powerpc-linux
-m32 due to accidentally changing the ABI.  By another historical
accident, complex long double is stupidly passed in gprs for -m32.

	* config/rs6000/rs6000.c (is_complex_IBM_long_double,
	abi_v4_pass_in_fpr): New functions.
	(rs6000_function_arg_boundary): Exclude complex IBM long double
	from 64-bit alignment when ABI_V4.
	(rs6000_function_arg, rs6000_function_arg_advance_1,
	rs6000_gimplify_va_arg): Use abi_v4_pass_in_fpr.
