WASM add option to build with native exceptions
Currently disabled, as literally no runtime has a working
implementation. It also currently conflicts with LLVM's SjLj
(AKA setjmp / longjump) when generating WASM bytecode, but
the only offending code doesn't use exceptions, so this can
be avoided in general.
