The "grow_memory" opcode was renamed to "memory.grow", and the spec repo was updated to use kExprMemoryGrow internally instead of kExprGrowMemory (https://github.com/WebAssembly/spec/pull/720). This CL does the same change for v8. Drive-by: Rename "current_size" to "memory.size", and a minor cleanup in wasm-graph-builder.js to bring it in line with the version in the js-api tests in the spec repo.
