[0xC] Convert to stack machine semantics. [0xC] Use section codes instead of names. [0xC] Add elements section decoding. [0xC] Decoding of globals section. [0xC] Decoding of memory section. [0xC] Decoding of imports section. [0xC] Decoding of exports section. [0xC] Decoding of data section. [0xC] Remove CallImport bytecode. [0xC] Function bodies have an implicit block. [0xC] Remove the bottom label from loops. [0xC] Add signatures to blocks. [0xC] Remove arities from branches. Add tests for init expression decoding. Rework compilation of import wrappers and how they are patched. Rework function indices in debugging. Fix ASM->WASM builder for stack machine. Reorganize asm.js foreign functions due to import indices change.
