[WebAssembly] Add support for weak symbols in the binary format This also introduces the updated format for the "linking" section which can represent extra symbol information.

[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] Remove debug names from symbol table Get rid of DEBUG_FUNCTION_NAME symbols. When we actually debug data, maybe we'll want somewhere to put it... but having a symbol that just stores the name of another symbol seems odd. It means you have multiple Symbols with the same name, one containing the actual function and another containing the name! Store the names in a vector on the WasmObjectFile when reading them in. Also stash them on the WasmFunctions themselves. The names are //not// "symbol names" or aliases or anything, they're just the name that a debugger should show against the function body itself. NB. The WasmObjectFile stores them so that they can be exported in the YAML losslessly, and hence the tests can be precise. Enforce that the CODE section has been read in before reading the "names" section. Requires minor adjustment to some tests. Patch by Nicholas Wilson!

[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.
