Optimize commutative operations in SkVM.
We now canonicalize commutative operations by ordering their value IDs.
The lower-numbered value ID is always placed first into a commutative
instruction. In other words, this instruction:
bit_and result, v7, v5
Would be silently converted to this:
bit_and result, v5, v7
This will allow these two logically-equivalent instructions to be
deduplicated:
bit_and result, v7, v5
bit_and result, v5, v7
Of course, deduplicating these ops can unlock additional free CSE/DCE.
The affected instructions are listed in http://review.skia.org/473238
