re PR target/25731 (Complex values passed in wrong registers)

	PR target/25731
	* config.gcc (hppa*-*-linux*, hppa[12]*-*-hpux10*, hppa*64*-*-hpux11*,
	hppa[12]*-*-hpux11*): Override default shared libgcc version for both
	sjlj and dwarf2 exception handling.
	* pa/t-hpux-shlib (SHLIB_SOVERSION): New make variable.
	Rework to allow overriding SHLIB_EXT and SHLIB_SOVERSION.
	* pa/pa.c (function_value): Treat complex and vector types as
	aggregates.
	(function_arg): Likewise.  Only pass scalar floats in the floating
	point argument registers.
	* pa/t-slibgcc-dwarf-ver: New file.
	* pa/t-slibgcc-sjlj-ver: New file.
	* pa/t-slibgcc-elf-ver: Delete file.
