Bug 1500167 - Support multiple tables in wasm. r=luke This is largely plumbing, and lots of it. The main complication is that function tables historically have had two representations: one optimized representation for tables that don't escape out of the instance, and one fatter representation for tables that do (and that must contain instance pointers). With multiple tables, we may table.copy from a function table with one representation to one with the other representation, in the limit this means changing the representation of the skinny table to be fat. However, at the time when we discover this, code may already have been generated that knows about the skinny representation, so we can't actually perform such a representation change. A somewhat reasonable solution to this is to just make all function tables fat - we're going to be changing things soonish anyway, when we make anyfunc / funcref a first-class type.

Bug 1450263 - Basic generalized table type, part 2: table.get/set/grow/size. r=luke Implement table.get, table.set, table.grow, and table.size, and also recognize GcFeatureOptIn version 2. The table operations except table.size and table.copy will fail validation on tables of anyfunc since we don't have any anyfunc values (and we won't accept null as an anyfunc value at the moment). Similarly, table.init will fail on tables of anyref since element segments can only reference functions and we don't yet accept anyfunc as a subtype of anyref.

Bug 1450263 - Basic generalized table type, part 1: table-of-anyref. r=luke We extend the concept of wasm tables: - table-of-anyref - "anyref" as type name for table elements in JS API The evolving spec for this feature is here: https://github.com/lars-t-hansen/moz-gc-experiments/blob/master/version2.md and is generally intended to track the evolving reftypes proposal. The generalized tables are under an ifdef that depend on the GC types ifdef. This is too restrictive; we will need to split the GC types ifdef into one for reftypes (to be enabled soon) and one for the rest of the GC feature (to be enabled later), and generalized tables only depend on the former. But that doesn't have to happen as part of this patch.
