[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] 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

[WebAssembly] MC: Create wasm data segments based on MCSections This means that we can honor -fdata-sections rather than always creating a segment for each symbol.

[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.

[WebAssembly] Add DataCount section to object files Summary: This ensures that object files will continue to validate as WebAssembly modules in the presence of bulk memory operations. Engines that don't support bulk memory operations will not recognize the DataCount section and will report validation errors, but that's ok because object files aren't supposed to be run directly anyway.
