(TARGET_DEFAULT,VALUE_REGNO,FUNCTION_VALUE_REGNO): Moved from unix target
files (aix386.h, i386gas.h, i386sun.h, i386v.h, i386v4.h, i386vgas.h,
seq386.h).
(TARGET_DEFAULT): Make TARGET_IEEE_FP default on.
(VALUE_REGNO): Test for MODE_FLOAT instead of specific modes.
(VALUE_REGNO,FUNCTION_VALUE_REGNO): MODE_FLOAT return reg depends on
TARGET_FLOAT_RETURNS_IN_80387.
