This patch renames the "Initial" member of WasmLimits to the name used
in the spec, "Minimum".
In the core WebAssembly specification, the Limits data type has one
required "min" member and one optional "max" member, indicating the
minimum required size of the corresponding table or memory, and the
maximum size, if any.
Although the WebAssembly spec does instantiate locally-defined tables
and memories with the initial size being equal to the minimum size, it
can't impose such a requirement for imports. It doesn't make sense to
require an initial size for a memory import, for example. The compiler
can only sensibly express the minimum and maximum sizes.
See
https://github.com/WebAssembly/js-types/blob/master/proposals/js-types/Overview.md#naming-of-size-limits
for a related discussion that agrees that the right name of "initial" is
"minimum" when querying the type of a table or memory from JavaScript.
(Of course it still makes sense for JS to speak in terms of an initial
size when it explicitly instantiates memories and tables.)

When we produce an YAML output, we also print leading zeroes currently.
An output might look like this:
```
- Name: .dynsym
Type: SHT_DYNSYM
Address: 0x0000000000001000
EntSize: 0x0000000000000018
```
There are probably no reason to print leading zeroes.
It just makes harder to read values. This patch stops printing them.
The output becomes like:
```
- Name: .dynsym
Type: SHT_DYNSYM
Address: 0x1000
EntSize: 0x18
```
This affects obj2yaml mostly, but also dsymutil and llvm-xray tools output.

Adds more testing in basic-assembly.s and a new test tables.s.
Adds support to yaml reading and writing of tables as well.

Summary:
Also changes the wasm YAML format to reflect the possibility of having
multiple return types and to put the returns after the params for
consistency with the binary encoding.

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.

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.

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.
