Rename memory instructions; Rework constant handling (#177)

Browse Source 
* Rename memory instructions as proposed by the bulk-memory-operations spec.
* Rename memory manager functions to memory.* as well
* Remove automatic inlining of constant globals (Binaryen does this now)
* Improve 'const' enum compatibility
* Improve module-level export generation
* Enable the inline decorator for constant variables
* Add ERROR, WARNING and INFO macros that emit a user-defined diagnostic
* Reintroduce builtin decorator so these can appear anywhere in stdlib again
* Inline isNaN and isFinite by default
* Make an interface around gc.* similar to memory.*
* Emit an error when trying to inline a mutable variable
* Slim down CI stages
* Add a more convenient tracing utility for debugging
* Implement some prequesites for an eventual bundled GC
