* 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
Starting with explicit loads and stores as part of the respective type namespaces. Might become handy for use with portable code, because these can be polyfilled, while load<T> and store<T> can't.
This catches the most common cases but doesn't yet implement inference involving the return type because some prequesites are not yet in place (see test case).
Remaining implementations of JavaScript's Math functions (except sin/cos/tan), both double (Math) and single (Mathf) precision, ported from musl incl. tests from libc-test, plus some changes to match JS semantics. Also binds fmod to `%` and pow to `**`.
