LLVM 14 doesn't support those build flags yet
(-no-opaque-pointers is the argument for -Xclang):
error: unknown argument: '-no-opaque-pointers'
Those build flags were added in the following commit:
003067c130
This fixes the following error:
configuring

It's a known upstream issue when building from the generated tarballs:
- https://bugs.chromium.org/p/chromium/issues/detail?id=1313361
- https://chromium-review.googlesource.com/c/chromium/src/+/3457503
This fixes the following error during patchShebangs:
./third_party/dawn/third_party/webgpu-cts/tools/run_deno: unsupported interpreter directive "#!/usr/bin/env -S deno run --unstable --allow-read --allow-write --allow-env --allow-net=deno.land --no-check" (set dontPatchShebangs=1 and handle shebang patching yourself)
This fixes build errors like this:
error: Could not read profile ../../chrome/build/pgo_profiles/chrome-linux-4951-1649181099-528ef6669805f2d3db6f3ad7429cfa57a6078271.profdata: unsupported instrumentation profile format version
We already package the most recent stable LLVM version for Chromium but Google
relies on unreleased (Git) versions (thanks...). This isn't ideal but I
don't have the time to package yet another LLVM version so it'll have to
cut it for now.
See build/config/compiler/pgo/pgo.gni:
- 0 : Means that PGO is turned off.
- 1 : Used during the PGI (instrumentation) phase.
- 2 : Used during the PGO (optimization) phase.
With is_official_build the default is chrome_pgo_phase = 2.
