Fixes from Peter Schauer:
* config/mips/tm-mips.h (REGISTER_CONVERT_TO_TYPE,
REGISTER_CONVERT_FROM_TYPE): Swap words if target, not host,
is big-endian and if registers are 32 bits.
* mips-tdep.c (mips_print_register, mips_extract_return_value,
mips_store_return_value): Fix floating-point word-order problems on
little-endian targets introduced by changes of Mar 21.
