This patch prevents the compiler from calling the IEEE 128-bit emulation
functions with the vector value in both GPRs and vector registers due to the
fact that the library function did not have a prototype.

I have built the compiler with this patch and the previous subpatches (1-4).  I
have bootstrapped the compiler with all 16 subpatches installed, and there were
no regressions.  Is it ok to install in the trunk?

	* config/rs6000/rs6000.c (init_cumulative_args): Initialize
	libcall field in CUMULATIVE_ARGS.
	(rs6000_function_arg): Treat library functions as if they had
	prototypes to prevent IEEE 128-bit support functions from passing
	arguments in both GPRs and vector registers.
	(rs6000_arg_partial_bytes): Likewise.
