Prevent divide by zero for / and % operations in constant folding (previously caused compiler SIGFPE), instead "inf" is generated for both cases. This closes #124

Constant fold intrinsics if their arguments are constant. TODO: reference count intrinsics such that they're not generated unless they're used, currently when an intrinsic can be folded-away it's marked for generation and makes it to the final output binary even though it isn't used.

Added -Oconst-fold-dce (dead code elimination optimization for when constant expressions form the basis of the dead code, i.e if else with constant expression). Fixed deps and added documentation. Cleaned up folds for ir_value (can now use the same macros as the ast_value ones).

folding for lteqgt (less than equal to or greater than) operator a.k.a <=> which maps values to -1,0,1 depending on the result (think of the result as a troolan) .. it's a perl thing :P
