[PATCH] testsuite: pr59833.c and pr61441.c should use -fsignaling-nans

[Segher Boessenkool <segher@kernel.crashing.org>]

The testcases pr59833.c and pr61441.c check whether signaling NaNs as
input to some operation result in quiet NaNs.  Without -fsignaling-nans
this is not guaranteed to happen.  So, this patch add this option to
these testcases.

Tested on powerpc64-linux {-m32,-m64}, on aarch64-linux, and on
x86_64-linux (where there is no issignaling, huh -- I tested on gcc20).

Is this okay for trunk?

	* gcc.dg/pr59833.c: Add -fsignaling-nans to options.
	* gcc.dg/pr61441.c: Ditto.
