[WebAssembly] Use inline target tripple in test cases This is somewhat preferable since (in many cases) it allows llc to be run directly on the .ll files without having to pass the `-mtriple` argument. Differential Revision: https://reviews.llvm.org/D42438 llvm-svn: 323299

[WebAssembly] Remove final -wasm component of target triple. NFC. This has been the default for a while now. llvm-svn: 332009

[WebAssembly] Initial wasm linker implementation This linker backend is still a work in progress but is enough to link simple programs including linking against library archives. Differential Revision: https://reviews.llvm.org/D34851 llvm-svn: 318539

[WebAssembly] Remove special handling of entry point export. Its much easier to export it via setHidden(false), now that that is a thing. As a side effect the start function is not longer always exports first (becuase its being exported just like all the other function).

[WebAssembly] Add support for --gc-sections In this initial version we only GC symbols with `hidden` visibility since other symbols we export to the embedder. We could potentially modify this the future and only use symbols explicitly passed via `--export` as GC roots. This version of the code only does GC of data and code. GC for the types section is coming soon. Differential Revision: https://reviews.llvm.org/D42511 llvm-svn: 323842
