John Stiles 626dbe195a Add test for commutative operations in SkVM. 
SkVM should be able to optimize away these equivalent expressions:

	(intA & intB)   <->  (intB & intA)
	(intA ^ intB)   <->  (intB ^ intA)
	(intA | intB)   <->  (intB | intA)
	(intA + intB)   <->  (intB + intA)
	(intA * intB)   <->  (intB * intA)
	(intA == intB)  <->  (intB == intA)
	(intA != intB)  <->  (intB != intA)

These should be guaranteed by IEEE754 as well:

	(floatA + floatB)   <->  (floatB + floatA)
	(floatA * floatB)   <->  (floatB * floatA)

I've added a test to demonstrate existing behavior, which leaves these
optimizations on the table.
