softfloat: Fix float64_to_uint32_round_to_zero
The float64_to_uint32_round_to_zero routine is incorrect.
For example, the following test pattern:
425F81378DC0CD1F / 0x1.f81378dc0cd1fp+38
will erroneously set the inexact flag.
This patch re-implements the routine to use the float64_to_uint64_round_to_zero
routine. If saturation occurs we ignore any flags set by the
conversion function and raise only Invalid.
