[WebAssembly] MC: Use inline triple in test bitcode files This matches the CodeGen tests and makes it a little easy to run these from the command line manually. Differential Revision: https://reviews.llvm.org/D42440 llvm-svn: 323275

[WebAsembly] Update default triple in test files to wasm32-unknown-unkown. Summary: The final -wasm component has been the default for some time now. Subscribers: jfb, dschuff, jgravelle-google, eraman, aheejin, JDevlieghere, sunfish, llvm-commits Differential Revision: https://reviews.llvm.org/D46342 llvm-svn: 332007

[WebAssembly] MC: Include unnamed data when writing wasm files Also, include global entries for all data symbols, not just external ones, since these are referenced by the relocation records. Add a test case that includes unnamed data. Differential Revision: https://reviews.llvm.org/D33079 llvm-svn: 303915

[WebAssembly] Add first claass symbol table to wasm objects This is combination of two patches by Nicholas Wilson: 1. https://reviews.llvm.org/D41954 2. https://reviews.llvm.org/D42495 Along with a few local modifications: - One change I made was to add the UNDEFINED bit to the binary format to avoid the extra byte used when writing data symbols. Although this bit is redundant for other symbols types (i.e. undefined can be implied if a function or global is a wasm import) - I prefer to be explicit and consistent and not have derived flags. - Some field renaming. - Some reverting of unrelated minor changes. - No test output differences.
