operators.ml — Coverage report

(*
This module originated as a copy of interpreter/syntax/operators.ml in the
reference implementation. It is pulled in by the strong cohesion between
the operators and the AST. Not having this source file locally would mean
that it got basically replicated into the customModuleDecode.ml file.

Base revision: WebAssembly/spec@a7a1856.

The changes are:
  * Manual selective support for bulk-memory operations `memory_copy` and `memory_fill` (WebAssembly/spec@7fa2f20).
  * Support for passive data segments (incl. `MemoryInit`).

The code is otherwise as untouched as possible, so that we can relatively
easily apply diffs from the original code (possibly manually).
