 `BRANCHENTRY` bit denotes whether a given offset pair is a control flow source
 (branch or call instruction). If not set, it signifies a control flow target
 (basic block offset).

 `InputAddr` is omitted for equal offsets in input and output function. In this
 case, `BRANCHENTRY` bits are encoded separately in a `BranchEntries` bitvector.

 The table is emitted for hot fragments only. It contains `NumSecEntryPoints`
 offsets denoting secondary entry points, delta encoded, implicitly starting at zero.
