[rfa:sparc] Remove write_fp() from sparc-tdep.c

Hello,

The attached deletes the write_fp() function from the sparc-tdep.c code.

Ok?

Once this is in, I'll commit the other patch that simply deletes 
write_fp() from the architecture vector.

	* sparc-tdep.c (sparc64_write_fp): Delete.
	(sparc_push_dummy_frame): Replace write_fp call with code to store
	the FP directly.
	(sparc_gdbarch_init): Do not initialize write_fp.
