[WebAssembly] Initial WebAssembly support in clang This implements basic support for compiling (though not yet assembling or linking) for a WebAssembly target. Note that ABI details are not yet finalized, and may change. Differential Revision: http://reviews.llvm.org/D12002 llvm-svn: 246814

[WebAssembly] Remove uses of ThreadModel Summary: In the clang UI, replaces -mthread-model posix with -matomics as the source of truth on threading. In the backend, replaces -thread-model=posix with the atomics target feature, which is now collected on the WebAssemblyTargetMachine along with all other used features. These collected features will also be used to emit the target features section in the future. The default configuration for the backend is thread-model=posix and no atomics, which was previously an invalid configuration. This change makes the default valid because the thread model is ignored. A side effect of this change is that objects are never emitted with passive segments. It will instead be up to the linker to decide whether sections should be active or passive based on whether atomics are used in the final link.

[WebAssembly] Remove uses of ThreadModel Summary: In the clang UI, replaces -mthread-model posix with -matomics as the source of truth on threading. In the backend, replaces -thread-model=posix with the atomics target feature, which is now collected on the WebAssemblyTargetMachine along with all other used features. These collected features will also be used to emit the target features section in the future. The default configuration for the backend is thread-model=posix and no atomics, which was previously an invalid configuration. This change makes the default valid because the thread model is ignored. A side effect of this change is that objects are never emitted with passive segments. It will instead be up to the linker to decide whether sections should be active or passive based on whether atomics are used in the final link.

This does not enable any more functionality in LLVM/clang for now, but this is necessary to embed the info in the target features section, which is used by Binaryen and Emscripten.
