Looks like it's already merged, but, fwiw, lgtm.

Thanks. Forgot to update the burndown list.

* Clarify that wasm may be viewed as either an AST or a stack machine. (#686)

* Clarify that wasm may be viewed as either an AST or a stack machine.

* Reword the introductory paragraph.

* Add parens, remove "typed".

* Make opcode 0x00 `unreachable`. (#684)

Make opcode 0x00 `unreachable`, and move `nop` to a non-zero opcode.

All-zeros is one of the more common patterns of corrupted data. This
change makes it more likely that code that is accidentally zeroed, in
whole or in part, will be noticed when executed rather than silently
running through a nop slide.

Obviously, this doesn't matter when an opcode table is present, but
if there is a default opcode table, it would presumably use the
opcodes defined here.

* BinaryEncoding.md changes implied by #682

* Fix thinko in import section

* Rename definition_kind to external_kind for precision

* Rename resizable_definition to resizable_limits

* Add  opcode delimiter to init_expr

* Add Elem section to ToC and move it before Data section to reflect Table going before Memory

* Add missing init_expr to global variables and undo the grouped representation of globals

* Note that only immutable globals can be exported

* Change the other 'mutability' flag to 'varuint1'

* Give 'anyfunc' its own opcode

* Add note about immutable global import requirement

* Remove explicit 'default' flag; make memory/table default by default

* Change (get|set)_global opcodes

* Add end opcode to functions

* Use section codes instead of section names

(rebasing onto 0xC instead of master)

This PR proposes uses section codes for known sections, which is more compact and easier to check in a decoder.
It allows for user-defined sections that have string names to be encoded in the same manner as before.
The scheme of using negative numbers proposed here also has the advantage of allowing a single decoder to accept the old (0xB) format and the new (0xC) format for the time being.

* Use LEB for br_table (#738)

* Describe operand order of call_indirect (#758)

* Remove arities from call/return (#748)

* Limit varint sizes in Binary Encoding. (#764)

* Global section (#771)

global-variable was a broken anchor and the type of count was an undefined reference and inconsistent with all the rest of the sections.

* Make name section a user-string section.

* Update BinaryEncoding.md

* Update BinaryEncoding.md

* Use positive section code byte

* Remove specification of name strings for unknown sections

* Update BinaryEncoding.md

* Remove repetition in definition of var(u)int types (#768)

* Fix typo (#781)

* Move the element section before the code section (#779)

* Binary format identifier is out of date (#785)

* Update BinaryEncoding.md to reflect the ml-proto encoding of the memory and table sections. (#800)

* Add string back

* Block signatures (#765)

* Replace branch arities with block and if signatures.

Moving arities to blocks has the nice property of giving implementations
useful information up front, however some anticipated uses of this
information would really want to know the types up front too.

This patch proposes replacing block arities with function signature indices,
which would provide full type information about a block up front.

* Remove the arity operand from br_table too.

* Remove mentions of "arguments".

* Make string part of the payload

* Remove references to post-order AST in BinaryEncoding.md (#801)

* Simplify loop by removing its exit label.

This removes loop's bottom label.

* Move description of `return` to correct column (#804)

* type correction and missing close quote (#805)

* Remove more references to AST (#806)

* Remove reference to AST in JS.md

Remove a reference to AST in JS.md. Note that the ml-proto spec still uses the name `Ast.Module` and has files named `ast.ml`, etc, so leaving those references intact for now.

* Use "instruction" instead of "AST operator"

* Update rationale for stack machine

* Update Rationale.md

* Update discussion of expression trees

* Update MVP.md

* Update Rationale.md

* Update Rationale.md

* Remove references to expressions

* Update Rationale.md

* Update Rationale.md
