Check NAN values in fdiv tests

The new RISC-V ISA spec mandates NAN bit patterns.  This test checks to make
sure that those bit patterns come out of fsqrt(-1).  These pass on both spike
and Rocket.

An additional _DWORD_RESULT version of the FP test macros is added to
facilitate floating-point tests that compare against particular bit patterns.
