This is part of the effort to consolidate the ownership of
wasm instantiation/specialization parameters.
This change is focused solely on the interpreter part of that effort, to
verify we're not regressing performance in interpreter benchmarks.
There are two aspects being addressed:
- dataflow-wise, we always fetch the interpreter's memory view from the
runtime objects (i.e. WasmInstanceObject/WasmCompiledModule). This is
consistent with how other instance-specific information is obtained
(e.g. code, indirect functions).
- representation-wise, we do not reuse ModuleEnv/WasmInstance just for
the memory view, because it is surprising that other instance info isn't
accessed from there.
