Motivation for this change

I'm trying to keep the differences between 20.09 and nixos-unstable minimal. I didn't backport these patches right away as the last two Chromium updates needed to be merged more quickly for security reasons. A few (two?) Chromium patches are still missing for now.

Things done
  • Tested using sandboxing (nix.useSandbox on NixOS, or option sandbox in nix.conf on non-NixOS linux)
  • Built on platform(s)
    • NixOS
    • macOS
    • other Linux distributions
  • Tested via one or more NixOS test(s) if existing and applicable for the change (look inside nixos/tests)
  • Tested compilation of all pkgs that depend on this change using nix-shell -p nixpkgs-review --run "nixpkgs-review wip"
  • Tested execution of all binary files (usually in ./result/bin/)
  • Determined the impact on package closure size (by running nix path-info -S before and after)
  • Ensured that relevant documentation is up to date
  • Fits CONTRIBUTING.md.

So that it can be accessed via llvmPackages_11.clang-unwrapped.clang-tools-extra_src
(e.g. useful for nix-prefetch-url).

(cherry picked from commit 72cc4d2)
#100190)

A port of #85925 for LLVM 11 to enable CFI for Chromium.

This is required for features such as `-fsanitize=cfi` that (by default)
load the file `…/resource-root/share/cfi_blacklist.txt`.

(cherry picked from commit 03dd1b3)
(cherry picked from commit 7a30df9)
compiler-rt (and as a result clang) can't be build for i686 (as noticed here: #99984).
The patch adds the required variables and should result in the same behavior as in the nixpkgs-llvm10. It essentially forces to use i386 buildins when using i486, i586 or i686, which are not supported.

Fixes #100392

(cherry picked from commit 6948875)
Chromium 86.0.4240.75 builds fine without this patch. And since
WEBP_MAX_DIMENSION is the same in the system libwebp this patch should
not be required anymore (it was introduced in 06ec2a9, apparently to
fix the build).

(cherry picked from commit 015c5a2)
(cherry picked from commit 5742fcd)
(cherry picked from commit 8e861c0)
ld.gold runs out of memory on i686.

(cherry picked from commit c557c27)
Wanted to do this for a long time to collect important knowledge and
make it easier to pass maintainership.
Only time will tell if this'll be useful or become outdated instead.

(cherry picked from commit b36db49)
The gn version depends on the channel and new gn versions aren't always
backward compatible. Therefore we should also include it in
upstream-info.json (I've scoped it under "deps" as we'll likely have to
add more like this in the future).

(cherry picked from commit d7f5386)

This also contains #103294 and should be ready to test now (CI was fine until the timeout).

@Frostman could you test Chromium as usual?

I'll merge this right away due to #103595. CI was fine anyway (up to the timeout at least).

@primeos I have some problems with my setup - wasn't able to get it to finish state, will try to debug this weekend and hopefully will work fine for the next time.
