[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] Fix expected contents of relocations with addends This fixes issues found on the wasm waterfall related to relocations with addends. Undefined symbols, even those with addends should always have a provisional value of zero. At least this is what llvm emits (and I believe this is true for ELF too).

[WebAssembly] Initialize memory in start function Summary: - `__wasm_init_memory` is now the WebAssembly start function instead of being called from `__wasm_call_ctors` or called directly by the runtime. - Adds a new synthetic data symbol `__wasm_init_memory_flag` that is atomically incremented from zero to one by the thread responsible for initializing memory. - All threads now unconditionally perform data.drop on all passive segments. - Removes --passive-segments and --active-segments flags and controls segment type based on --shared-memory instead.

[WebAssembly] Update MC for bulk memory Summary: Rename MemoryIndex to InitFlags and implement logic for determining data segment layout in ObjectYAML and MC.
