Translate from the i386. All FP constants and operations are evaluated
in the range and precision of their type(s) on amd64, but FLT_EVAL_METHOD
said that they were evalated in the "interesting" (buggy) i387 methods.
float_t was broken compatibly with FLT_EVAL_METHOD.
These definitions seem to be broken on powerpc and possibly on arm.
float_t is float on powerpc with gcc [-notraditional] according to
glibc, and FLT_EVAL_METHOD is marked with XXX on arm.
