Andreas Haas 4fc90a2597 [wasm] Refactor trap-handler to allow an extension to windows 
This CL refactors the existing trap handler code for Linux to allow a
cleaner extension to Windows.

1) The CL extracts platform-specific code into separate files, see
https://docs.google.com/document/d/1HCgKIpdjy_CEodTLvZ5VuykDI6gGTHrTtau2j0zwm28.
Specifically this means:
* Move posix-specific API functions from v8.h to v8-wasm-trap-handler-posix.h.
  Deprecate the existing TryHandleSignal API function.
* Move posix-specific function declarations from trap-handler-internal.h to
  handler-inside-posix.h
* Move posix-specific function definitions from handler-shared.cc to
  handler-outside-posix.cc

2) The CL changes filenames from *-linux.* to *-posix.*. I expect that
most of the implementation for MacOS will be the same as for Linux.

    git pull origin
    gclient sync

For fetching all branches, add the following into your remote configuration in .git/config:

    fetch = +refs/branch-heads/*:refs/remotes/branch-heads/*
    fetch = +refs/tags/*:refs/tags/*
