[WebAssembly] Add linking metatdata test coverage for wasm2yaml Subscribers: jfb, dschuff, jgravelle-google, aheejin, sunfish Differential Revision: https://reviews.llvm.org/D41196 llvm-svn: 320639

[WebAssembly] Explicitly specify function/global index space in YAML These indexes are useful because they are not always zero based and functions and globals are referenced elsewhere by their index. This matches what we already do for the type index space. Differential Revision: https://reviews.llvm.org/D41877 llvm-svn: 322121

[WebAssembly] Update MC for bulk memory Summary: Rename MemoryIndex to InitFlags and implement logic for determining data segment layout in ObjectYAML and MC. Also adds a "passive" flag for the .section assembler directive although this cannot be assembled yet because the assembler does not support data sections.

[WebAssembly] Store section alignment as a power of 2 This change bumps for version number of the wasm object file metadata. See https://github.com/WebAssembly/tool-conventions/pull/92 Differential Revision: https://reviews.llvm.org/D56758 llvm-svn: 351285

[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.
