softfloat: Fix float64_to_uint64_round_to_zero
The float64_to_uint64_round_to_zero routine is incorrect.
For example, the following test pattern:
46697351FF4AEC29 / 0x1.97351ff4aec29p+103
currently produces 8000000000000000 instead of FFFFFFFFFFFFFFFF.
This patch re-implements the routine to temporarily force the
rounding mode and use the float64_to_uint64 routine.
This contribution can be licensed under either the softfloat-2a or -2b
license.
