Reland "Roll src/buildtools/third_party/libc++/trunk/ 79a2e924d..b1269813e (1399 commits)"

This is a reland of 3a28cd7fbcbf1e58c88c3ac756eaef69d0676eda

Changes:
* Add some additional tryjobs
* Disable debug mode when using LTO as it seems to break with
  https://reviews.llvm.org/D103964 (https://crbug.com/1327706)
* Define _LIBCPP_ABI_NAMESPACE for Windows to resolve a PDB size issue
  (http://crbug.com/1327710).

> > We deliberately roll libc++ to b1269813eaf5 (~1.5 months old at the
> time
> > of this commit) rather than the latest version of libc++ in order to
> > deliberately avoid https://reviews.llvm.org/D122982, which causes a
> > potentially disruptive performance regression in Chrome
> > (https://crbug.com/1322961). https://reviews.llvm.org/D124328 is

> > past it again.
> >
> > Additional changes made to get this CL to pass presubmits:
> >
> > * Set _LIBCPP_ABI_VERSION=2 and _LIBCPP_ABI_NAMESPACE due to
> >   _LIBCPP_ABI_UNSTABLE being removed in
> >   https://reviews.llvm.org/D119173.
> > * Regenerate gvr-android-sdk prebuilts.
> > * Updates to libc++'s BUILD.gn to handle new files in libc++.
> > * Update check_static_initializers.py test since init_priority was
> >   changed from 101 to 100 in https://reviews.llvm.org/D95972.
> > * Miscellaneous increments to #pragma clang_max_tokens_here.

Binary-Size: The increase is caused by https://reviews.llvm.org/D113413, which changed the implementation of std::sort(...) in libc++. This is a necessary change to keep libc++ up-to-date.
