Fix for fuzzer-discovered crash with swizzles. We need to rescan after optimizing away expressions that might exist in the CFG/definition map, since we are rebuilding them from scratch and not just stripping off excess parts from them.

Update tests which mix int and float types without casts. These need to change because type coercion in SkSL is about to become more strict in a followup CL; we are disallowing expressions that mix ints and floats without a cast.
