Fix complex floats on sparc.

* sparc-tdep.h (SPARC_F2_REGNUM, SPARC_F3_REGNUM, SPARC_F4_REGNUM,
	SPARC_F5_REGNUM, SPARC_F6_REGNUM, SPARC_F7_REGNUM): New enums.
	* sparc-tdep.c (sparc_complex_floating_p): New function.
	(sparc32_store_arguments): Handle complex floats.
	(sparc32_extract_return_value): Likewise.
	(sparc32_store_return_value): Likewise.
	(sparc32_stabs_argument_has_addr): Likewise.
	* sparc64-tdep.c (sparc64_complex_floating_p): New function.
	(sparc64_store_floating_fields): Handle complex floats.
	(sparc64_store_arguments): Likewise.
	(sparc64_store_return_value): Likewise.
