Title: Test drawArrays and drawElements with non-zero divisor

ANGLE_instanced_arrays spec redefines drawArrays and drawElements in the
terms of drawArraysOneInstance and drawElementsOneInstance, so vertex
attrib divisors should affect them too. Test this.

Includes some minor code cleanup as well.
