[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] Allow function signature checking at link time This change allows checking of function signatures but does not yes enable it by default. In this mode, linking two objects that were compiled with a different signatures for the same function will produce a link error. New options for enabling and disabling this feature have been added: (--check-signatures/--no-check-signatures). Differential Revision: https://reviews.llvm.org/D40371 llvm-svn: 319396
