[svn-r10931] Purpose: Adjust Test Program and Rename
Description: Renamed test/dt_atomic.c to test/dt_arith.c(an abbreviation of "arithmetic data types") to better describe the program. This checkin broke down into three sections when the floating-point numbers are the source, normalized, denormalized, and special values. If there's any difference of destination values, only normalized value test reports failure. The other 2 report only as warning. Platforms tested: h5commitest and fuss Misc. update: MANIFEST
