Spoike 62a4572f23 Fix some -TFTE issues with xonotic. 
Implement OP_STOREF_F, but don't generate it just yet (waiting for next 'stable' build).
Just disable fteqcc.log by default. If this affects adversely you then you should probably just be using fteqccgui instead.

//qc execution code.
//we have two conditions.
//one allows us to debug and trace through our code, the other doesn't.
//hopefully, the compiler will do a great job at optimising this code for us, where required.
//if it dosn't, then bum.
//the general overhead should be reduced significantly, and I would be supprised if it did run slower.
//run away loops are checked for ONLY on gotos and function calls. This might give a poorer check, but it will run faster overall.
//Appears to work fine.
