This PR, in theory, allows more code to be jitted.
EXIT_IFbranches to a side exit, allowing it to be jitted once it has warmed up, whereDEOPT_IFalways exits to the interpreter.In practice this doesn't seem to make much difference, but it does unblock other work to jit more code.
Performance is generally neutral, less than 1% faster or slower across 5 different platforms.
