Clang >= 11 ignores PYTHON_EXECUTABLE entirely (and uses python3, which
is not even what we pass, but that's actually fine), and all the build
tasks we have on older versions find the python executable they need on
their own.

After changeset 5e4b33fe9218703f0b29e2446159bcf4202d15fa the Attributes.cpp file was
changed so our patched version was not sticking on top of it. This patch does the proper
rebase.

- we needed -gcc-toolchain to pick C/C++ standard headers from the right
version of GCC, but we now have them in the toolchain sysroot (bug
1719207), so we can use that instead.
- we needed LD_LIBRARY_PATH when clang was built on an older version of
Debian, but that was changed in bug 1694775.

We have a separate binutils toolchain already, and the only remaining
use of the binutils part of the the GCC toolchain is for the gold plugin
headers for clang, which we can add to the toolchain sysroot.

Sometimes there is a deadlock between user-requested ccov counters flush (through a signal) and flush happening when a process is dying.
So in order to avoid it, just remove the latter which is out of our control (user-requested flushes are protected using a cross mutex).

We should probably enable this later on when we do the aproapriate fixes in m-c and they
are also tagged in m-r but for now we should have this changed backed out of llvm locally.

1. Add task to get and build clang from the main branch.
2. Using clang main toolchain we build on a daily basis linux64 firefox, this tasks also automatically triggers the fetch and build of clang from main branch since we don't cache it.

Our bot was expecting to have tasks that were succeeding, right now we no longer need that
and in a case of a build failure, or in a case of the presence of a checker that asserts itself
as error and not warning we should mark the task red by failing the job.

Just adding the toolchain tasks for now. They are not yet used by anything, but bug 1693288 might be interested eventually.
As with earlier releases, clang-tidy and mingw builds are not included here, they'll be separate patches.

We've been building clang with SDK 10.12 since bug 1680152, but the
build-clang script is still assuming we're building with an older one.

Because of conflicts between gcov_flush from gcc and the one from llvm, we renamed llvm one into ___custom_llvm_gcov_flush.
Since we switched to clang for linux ccov builds, this workaround is now useless.

When using the --sysroot argument to clang, clang changes where it
searches for libraries in its own directory, and excludes the lib and
lib32 subdirectories. So we need to move the gcc files to a place where
it does look (and that it also looks without --sysroot).
We however still keep a copy of libstdc++ in the lib directory for
runtime purposes.

I missed these in bug 1682405.
Additionally, after this removal, llvmorg-10-init-5191-ga84b200e604-windows-pgo.patch also becomes unused, so it is deleted too.

In addition to the usual dot-release type of fixes, this also lets us drop a good amount of code that we had patched into our clang 11.

At this point it's pretty clear that we won't be reverting to clang-9.
This doesn't remove everything with clang-9 in the name. I did a mark-and-sweep GC by hand so this only removes unused entries. Some are still active, e.g. linux64-clang-9 is used to build a number of misc helper tools.

Currently, in LTO builds, we use the new pass manager during the initial translation to bitcode but not for the final optimization during linking.
On Linux, we can enable the new pass manager during LTO with a plugin option. I've landed a patch upstream to allow it on Windows as well, which is included here.
Switching the pass manager brings speed improvements on its own, but it also reduces code size by ~6%, which we can use a portion of as budget to increase the import limit (via the hot multiplier) for even more speed improvements.
