* i387-tdep.c, i386-tdep.c i386v-nat.c, i386aix-nat.c, 

i386m3-nat.c, config/m68k/tm-m68k.h, i960-tdep.c
	config/i960/tm-i960.h, remote-nindy.c, config/m88k/tm-m88k.h,
	m88k-tdep.c: Use floatformat.h instead of ieee-float.h.
	* sparc-tdep.c: Remove now-obsolete ieee-float.h stuff
	* findvar.c: Update comment regarding ieee-float.h.

formats. So if host is IEEE floating and target is VAX floating,
or vice-versa, it loses. This means that we can't (yet) use these
routines for extendeds. Extendeds are handled by
REGISTER_CONVERTIBLE. What we want is a fixed version of
ieee-float.c (the current version can't deal with single or double,
and I suspect it is probably broken for some extendeds too).
REGISTER_CONVERTIBLE. What we want is to use floatformat.h, but that
doesn't yet handle VAX floating at all.
2. We can't deal with it if there is more than one floating point
format in use. This has to be fixed at the unpack_double level.
