move more parser code to c++, fix crashes with gcc
...
we initialized the parser with malloc -> memset to zero ->
placement new. With gcc the latter caused the memset to be
optimized out, causing uninitialized value accesses.

Perliminary work on arithmetic exception handling in the constant evaluator. We can safely check for arithmetic underflow, overflow, divison by zero and inexactness now. Inexactness of expressions are propagated through the AST such that using an inexact value in a comparison will trigger a warning with -Winexact-compares.

Some intrinsic code cleanup. The args check is handled anyways in the parser. We use a generated array alongside to prevent generating the intrinsic multiple times instead of using static storage. Other various cleanups as well.

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.
