55fc5c0c32 [wasm] Rename wasm::LocalType to wasm::ValueType and kAst* to kWasm*
This is more renaming work to comply with the naming in the public
design repository. E.g. types are called "value types" and we no longer
refer to ASTs.

b5c69cbf39 [builtins] NonNumberToNumber and StringToNumber now use CallRuntime instead of TailCallRuntime
With the tail call, pointers to the JS heap could be pushed on a
js-to-wasm frame. On the js-to-wasm frame, however, this pointer would
not be updated by the GC.

2aa4656eeb [wasm] Binary 11: WASM AST is now postorder.
[wasm] Binary 11: br_table takes a value.
[wasm] Binary 11: Add implicit blocks to if arms.
[wasm] Binary 11: Add arities to call, return, and breaks
[wasm] Binary 11: Add experimental version.

This CL changes the encoder, decoder, and tests to use a postorder
encoding of the AST, which is more efficient in decode time and
space.
