Change the calling convention for BIFs

The current calling convention for BIFs makes it necessary to
handle each arity specially, since each argument for the BIF
also becomes an argument for the C function implementing the BIF,
which makes it hard to allow BIFs with any number of arguments.

Change the calling convention for BIFs, so that BIF arguments are
passed in an array to the C function implementing the BIF.
