Heejin Ahn da419bdb5e [WebAssembly] Add support for the event section
Summary:
This adds support for the 'event section' specified in the exception
handling proposal. (This was named 'exception section' first, but later
renamed to 'event section' to take possibilities of other kinds of
events into consideration. But currently we only store exception info in
this section.)

The event section is added between the global section and the export
section. This is for ease of validation per request of the V8 team.

This patch:
- Creates the event symbol type, which is a weak symbol
- Makes 'throw' instruction take the event symbol '__cpp_exception'
- Adds relocation support for events
- Adds WasmObjectWriter / WasmObjectFile (Reader) support
- Adds obj2yaml / yaml2obj support
- Adds '.eventtype' printing support

Thomas Lively a0d25815a0 [WebAssembly] v8x16.shuffle
Summary:
Since the shuffle mask is not exposed as an operand in the native ISel
DAG, create a new WebAssembly ISD node exposing the mask. The mask is
lowered as sixteen immediate byte indices no matter what type the
original vector shuffle was operating on.

This CL depends on D51656

Adrian Prantl 5f8f34e459 Remove \brief commands from doxygen comments.
We've been running doxygen with the autobrief option for a couple of
years now. This makes the \brief markers into our comments
redundant. Since they are a visual distraction and we don't want to
encourage more \brief markers in new code either, this patch removes
them all.

  for i in $(git grep -l '\\brief'); do perl -pi -e 's/\\brief //g' $i & done

Dan Gohman 950a13cfa3 [WebAssembly] Check in an initial CFG Stackifier pass
This pass implements a simple algorithm for conversion from CFG to
wasm's structured control flow. It doesn't yet handle multiple-entry
loops; that will be added in a future patch.

It also adds initial support for switch statements.
