Heejin Ahn	e2f3e50df6	[WebAssembly] Check if the section order is correct ... Summary: This patch checks if the section order is correct when reading a wasm object file in `WasmObjectFile` and converting YAML to wasm object in yaml2wasm. (It is not possible to check when reading YAML because it is handled exclusively by the YAML reader.) This checks the ordering of all known sections (core sections + known custom sections). This also adds section ID DataCount section that will be scheduled to be added in near future.

Jonas Devlieghere	7689b8dd09	[WASM] Fix overflow when reading custom section ... When reading a custom WASM section, it was possible that its name extended beyond the size of the section. This resulted in a bogus value for the section size due to the size overflowing.
