At least based on the lit tests, the coalescer sometimes fails to propagate the copy from X0 into the branch instruction. This patch does it manually during isel. The majority of the changes are from the select patterns. Some of the changes are just register allocation changes. Only the Select change affects the whether a b*z instruction is generated in the tests. I changed the branch pattern for consistency.
