fe15364988 Improve performance of R6RS records implementation
Reimplement record-type descriptors as vtables for record structs, saving
us what was an expensive inspection of a record's vtable layout string to
determine its type.

* module/rnrs/records/inspection.scm (record-field-mutable?): Check
  mutability using the bit field stored in the record-type descriptor
  instead of the record struct's vtable.
* module/rnrs/records/procedural.scm (record-internal?): Reimplement as a
  delegation to a check of the passed struct's vtable against
  `record-type-descriptor?'.
  (record-type-vtable): Modify to include base vtable layout as a prefix
  of the record-type-descriptor layout so that all record-type instances
  are now also vtables.
  (make-record-type-descriptor): Remove field vtable; build up a mutability
  bit field to use for fast mutability checks.
  (record-accessor, record-mutator): Use field struct and mutability bit
  field.

e44d2e4d98 remove encoding of versions into the file system (for now?)
* module/ice-9/boot-9.scm (find-versioned-module): Remove. Still had
  some bugs (e.g. for "." in the path and in finding compiled files),
  did too much computation and statting, and we don't really want to
  promote versioning. Nor do we want to hard-code a particular encoding
  of versions in the file-system. Perhaps the real way to do this is to
  be extensible somehow.
  (try-module-autoload): Just dispatch to primitive-load-path in all cases.
