[perl #51634] [BUG] docs/parrotbyte.pod && docs/pdds/pdd13_bytecode.pod are either incorrect/unclear

This appears to still be an issue.  Here is the relevant section from
docs/pdds/pdd13_bytecode.pod:

483 =head3 Fixup Segment
 484 
 485 The fixup segment maps names of subs to offsets in the bytecode
stream. It
 486 adds one extra field to its header.
 487 
 488 {{ TODO: I think label fixups are no longer used. Check if that is
so. }}

 491   | Offset | Length | Description

 493   | 1      | 1      | Number of fixup table entries that follow.  
          |

 497 This is followed by n fixup table entries, of variable length, that
take the
 498 following form.

 503   | 0      | 1      | Type of the fixup. Must be:

 504   |        |        |    0x01 - Subroutine fixup

 506   | 1      | 1      | The label that is being fixed up. A string
constant,   |
 507   |        |        | stored as an index into the constants table.
          |
 508

 509   | 2      | 1      | For subroutine fixups, this is an index into
the       |
 510   |        |        | constants table for the sub PMC corresponding
to the   |
 511   |        |        | label.
