Seems like there is a similar setting for the FPU, too:

 fpu_no_unimplemented

.... should we also initialize that to "true"?

Another observation: "fpu_strict" seems to be only used by the JIT code
which we do not use yet. Shall we disable that "FPU slower but more
compatible" setting in the GUI? (and maybe also the "--fpu-compatible"
CLI option?)
