[svn-r11355] Purpose: A new API function and its test.

Description:  Put in a new API funciton, H5Tis_hard.  It checks whether
the conversion function from a native type to another native type is a
compiler (hard) conversion.  Also checked a test in test/dt_arith.c.


Platforms tested: h5committest and fuss.
