Remove --with-mixedrefs configuration option

The default behavior will remain unchanged: to produce a VM which
supports both compressed and non-compressed references.

Support for non-compressed references only is available, as before,
by using the '--with-noncompressedrefs' configuration option.

Support for compressed references only is now available by using the
configuration option '--with-noncompressedrefs=no' (instead of
'--with-mixedrefs=no').
