update bootstrap to work for macos too

 * Directives can have arbitrary expressions as parameters
 * Fix switch statement not generating code sometimes
 * Rename "main" fn in bootstrap.zig to "zig_user_main" to
   avoid name collisions
 * codegen: fix badref when unreachable is last thing in an
   expression
 * support #condition directive on exported functions
