Reland of Switch Chrome on Linux to libc++ (patchset #1 id:1 of https://codereview.chromium.org/2965693002/ )

Reason for revert:
ANGLE compilation issues should be fixed by https://chromium-review.googlesource.com/557679

> > In addition, this CL updates perf_expectations to increase the number
> > of allowed static initializers.  libc++ adds some initializers from
> > iostream.cpp.  However, this case is net-neutral since the initializer
> > used to live in libstdc++, but has been pushed into the chrome and
> > nacl executables.  The perf_expectations change also required adding
> > NOPRESUBMIT=true to silence a bogus warning.
