[WebAssembly] Adding 64-bit versions of __stack_pointer and other globals We have 6 globals, all of which except for __table_base are 64-bit under wasm64. Differential Revision: https://reviews.llvm.org/D82130

[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.

[WebAssembly] Rename relocations from R_WEBASSEMBLY_ to R_WASM_ See https://github.com/WebAssembly/tool-conventions/pull/95. This is less typing and IMHO more readable, and it also fits with our naming around the binary format which tends to use the short name. e.g. include/llvm/BinaryFormat/Wasm.h tools/llvm-objdump/WasmDump.cpp etc..
