tests for fenv.h functions

added tests for fesetexeptflag(), fegetexeptflag(),
fegetround(), fesetround().

In the test fegetround() does not return any flag
other then FE_TONEAREST in tests.
This is probably due to soft float.

The test complies successfully and returns assert
at fegetround()

Other tests run without any errors
tested on RISCV/rv32imac

The test prints nothing if runs successfully.

updates #2971
