The path to built libyuv lib has changed after the
"win: Rename clang_x64 to win_clang_x64 in build/toolchain/win"
has landed. See https://crbug.com/748501.

These changes are just backported from the newer Chromium revision.
Some of the patches (maybe even all) should be removed during
the next Chromium upgrade.

    And remove the local patch

It seems like sysroot is expected to have it but it doesn't.
We should probably upstream this change or update the sysroot.

We've got a new sysroot from the upstream, but not the code fixes.
This patch should be removed after the upgrade to Chromium 63 or 64.

Node.js was updated in the master, we have to remove
V8's patches added during that update.
Those patches are either not needed for the Node.js 9.2.1,
or were already added in the Ch62 upgrade branch.

This is needed for service worker scripts, whose behavior was changed with
script streaming https://chromium-review.googlesource.com/c/chromium/src/+/597033
