This patch adds a way for users to create their own custom sections to be added to wasm files. At the LLVM IR layer, they are defined through the "wasm.custom_sections" named metadata. The expected use case for this is bindings generators such as wasm-bindgen. Patch by Dan Gohman Differential Revision: https://reviews.llvm.org/D45297 llvm-svn: 329315
