* alpha-tdep.c: Move sigtramp handling of saved registers from

Browse Source 
read_next_frame_reg to alpha_find_saved_regs, handle saved
	floating point registers.
	* mips-tdep.c:  Move sigtramp handling of saved registers from
	read_next_frame_reg to mips_find_saved_regs, handle saved
	floating point registers.
	* config/mips/tm-irix3.h, config/mips/tm-irix5.h,
	config/mips/tm-mipsv4.h (SIGFRAME_FPREGSAVE_OFF):  Define.

	* sparc-tdep.c (sparc_pc_adjust):  Fix check for `unimp'
	instruction to handle functions returning structures with
	large sizes properly.
