Make SCM_NUMP and SCM_NUMBERP more extensible

* libguile/numbers.h (SCM_NUMP, SCM_NUMBERP): Mask out more bits in the
  cell type field when doing the comparison, in order to accept future
  numeric types that have not yet been implemented.  This should allow
  us to add more core numeric types without breaking ABI compatibility.
  As a bonus, these macros are now more efficient.
