* (nindy_fetch_registers nindy_store_registers): Get rid of fp
conversion code. That's all handled in {extract store}_floating
now.
* utils.c (floatformat_to_double): Don't bias exponent when
handling zero's, denorms or NaNs.
* config/i960/tm-i960.h (REGISTER_CONVERT_TO_VIRTUAL
REGISTER_CONVERT_TO_RAW): Change to using DOUBLST and
FLOATFORMAT_TO/FROM_DOUBLEST macros.
* config/i960/tm-nindy960.h: Undefine
REGISTER_CONVERT_TO_VIRTUAL, REGISTER_CONVERT_TO_RAW, and
REGISTER_CONVERTIBLE. These are no longer necessary now that all
the magic happens in extract/store_floating.
config files moved to an appropriate config/<cpu> subdirectory.
* nm-*, xm-*, tm-*: All native, host, and target files, which
get linked to nm.h, xm.h, and tm.h respectively by configure,
