tree-ssa-math-opts: Use element_precision.

The recent TYPE_PRECISION changes to detect improper usage
cause an ICE in divmod_candidate_p for RVV when called with
a vector type.  Therefore, use element_precision instead.

gcc/ChangeLog:

	* tree-ssa-math-opts.cc (divmod_candidate_p): Use
	element_precision.
