arm: make some hardcode values runtime configurable

These are undocumented, but allow running (untested) optimizations that should be available in modern arm environments. These are: o jit_cpu.exchange: If set to zero, will not use indirection for function calls to switch from arm to thumb mode. This is a global flag and only meaningful if generating thumb instructions (default) if available. o jit_cpu.version and jit_cpu.extend: If jit_cpu.version is >= 7 and jit_cpu.extend is 1, it will generate thumb integer divide instructions. Only meaningful for thumb mode. Note that modulo (or rem as called in lightning) still uses a C function call.
