With fix of uninitialized variable.
Original commit message:
This change is intended to use for LLD in D33183.
Problem we have in LLD when building .gdb_index is that we need to know section which address range belongs to.
Previously it was solved on LLD side by providing fake section addresses with use of llvm::LoadedObjectInfo
interface. We assigned file offsets as addressed. Then after obtaining ranges lists, for each range we had to find section ID's.
That not only was slow, but also complicated implementation and was the reason of incorrect behavior when
sections share the same offsets, like D33176 shows.
This patch makes DWARF parsers to return section index as well. That solves problem mentioned above.

Previously we had only supported the importing and
exporting of functions and globals.
Also, add usefull overload of getWasmSymbol() and
getNumberOfSymbols() in support of lld port.

Summary:
Addends are used as offsets to addresses of globals
and can be both positive and negative. This change
prints libObject in line with the spec and the MC
layer.

Mostly this change adds support converting to and from
YAML which will allow us to write more test cases for
the WebAssembly MC and lld ports.
Better support for objdump, readelf, and nm will be in
followup CLs.
I had to update the two wasm test binaries because they
used the old style 'name' section which is no longer
supported.

The file does not seems to use c++ iostreams (and is is llvm policy to avoid
that). Committing as obvious.
