gimple: Add assert for code being a comparison in gimple_cond_set_code

We have code later on that verifies the code is a comparison. So let's
try to catch it earlier. So it is easier to debug where the incorrect code
gets set.

Bootstrapped and tested on x86_64-linux-gnu.

gcc/ChangeLog:

	* gimple.h (gimple_cond_set_code): Add assert of the code
	being a comparison.
