[WebAssembly] Added default stack-only instruction mode for MC. Summary: Made it convert from register to stack based instructions, and removed the registers. Fixes to related code that was expecting register based instructions. Added the correct testing flag to all tests, depending on what the format they were expecting so far. Translated one test to stack format as example: reg-stackify-stack.ll tested: llvm-lit -v `find test -name WebAssembly` unittests/MC/* Reviewers: dschuff, sunfish Subscribers: sbc100, jgravelle-google, eraman, aheejin, llvm-commits, jfb Differential Revision: https://reviews.llvm.org/D51241 llvm-svn: 340750

[WebAssembly] Add mechanisms for specifying an explicit import module name. This adds a wasm-import-module function attribute and a .import_module assembler directive, for specifying module import names for WebAssembly. Currently these may only be used for function symbols; global variables may be considered in the future. WebAssembly has a two-level namespace scheme for symbols, and it's normally the linker's job to assign the module name, which is the first-level name. The attributes here allow users to specify their own module names explicitly, which is useful for tools generating bindings to modules defined in other languages. This feature is not fully usable yet. It will evolve along with the ongoing symbol table and lld changes. Differential Revision: https://reviews.llvm.org/D42520 llvm-svn: 324778
