[WebAssembly] MC: Fix value of R_WEBASSEMBLY_TABLE_INDEX relocations Previously we were writing the value function index space value but for these types of relocations we want to be writing the table element index space value. Add a test case for these relocation types that fails without this change. Differential Revision: https://reviews.llvm.org/D33962 llvm-svn: 305253

[WebAssembly] Use __stack_pointer global when writing wasm binary This ensures that symbolic relocations are generated for stack pointer manipulations. These relocations are of type R_WEBASSEMBLY_GLOBAL_INDEX_LEB. This change also adds support for reading relocations of this type in WasmObjectFile.cpp. Since its a globally imported symbol this does mean that the get_global/set_global instruction won't be valid until the objects are linked that global used in no longer an imported global.
