Add caching. (#134)

Browse Source 
* Allow a module to have a different signature registry than the process-specific

* Add core ability to build compiled code caches

* Remove timing printouts

* Serialize/Deserialize memories to reduce copies

* Work more on api

* Relocate local functions relatively before external functions

* Fix incorrect definition in test

* merge errors caused by merge

* Fix emscripten compile

* Fix review comments
