Add support for record types with anonymous fields
Avoid saving a list of per-field vector descriptions when field names are not going to be relevant and the rest of the description is easily computed from information that is alerady available. original commit: a20e3f305cee3b4a386582dd50cda344a49174c3

This variant of \scheme{make-record-type-descriptor} accepts a field
|
||||
count and mutability mask in place of a vector of field descriptions,
|
||||
which results in a record type with anonymous fields. The \var{fields}
|
||||
argument must be a non-negative fixnum for the field count, and it is
|
||||
added to any fields present in \var{parent} to determine the record
|
||||
type's total numnber of fields. The \var{mutability} argument must be
|
||||
an exact non-negative integer that is treated as a bit array; a
|
||||
\scheme{1} bit indicates the the corresponding field among
|
||||
\var{fields} is mutable.
|
||||
|
||||
If \var{parent} is a record type descriptor, it must also have
|
||||
anonymous fields. The resulting anonynmous-field record type can only
|
||||
be the parent of a record type with anonymous fields.
