* defs.h, findvar.c (extract_floating, store_floating): New functions.

Browse source 
* Move SWAP_TARGET_AND_HOST from defs.h to findvar.c because it is
	now used only by extract_floating and store_floating.
	* valprint.c (print_floating): Use unsigned arithmetic.  Use
	extract_unsigned_integer instead of SWAP_TARGET_AND_HOST.
	Change sizeof (float) to 4 and sizeof (double) to 8 (those are always
	the relevant sizes for this code, which is in #ifdef IEEE_FLOAT).
	* values.c (unpack_long, unpack_double, value_from_double),
	valarith.c (value_binop), stabsread.c (define_symbol):
	Use extract_floating and store_floating instead of
	SWAP_TARGET_AND_HOST.
	* config/m68k/tm-m68k.h, config/i960/tm-i960.h (REGISTER_CONVERT_*):
	Use extract_floating and store_floating.
	* config/m88k/tm-m88k.h: Add comments (it should be doing the same).
	* i386-tdep.c (i386_extract_return_value),
	* remote-nindy.c (nindy_store_registers): Use store_floating.
