Sam Clegg 6f08c84ae5 [WebAssembly] Use section index in relocation section header
Rather than referring to sections my their code, use the
absolute index of the target section within the module.

Sam Clegg 6c899ba6de [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.

Sam Clegg 8bda508b7b [WebAssembly] Be consistent in generating trivial test input files
For each checked-in wasm file, make sure the there is
corresponding .ll file that can be used to regenerate it
if needed.

Add test/Object/Inputs/trivial-object-test.wasm to match other
formats and add some new wasm tests in test/Object.
