3. Original pull request related commit(s):
Ascend950 does not support saturation mode. When users set
INF_NAN_MODE_ENABLE=0 or INF_NAN_MODE_FORCE_DISABLE=1 on Ascend950,
the code incorrectly falls into saturation mode path, causing
RuntimeError: SET StreamOverflowSwitch Failed.
Add early return in IsSupportInfNan() for Ascend950 to always return
true, making both env vars ineffective on this device.
