[Release-testers] 13.0.0-rc1 has been tagged

[Albion Fung via Release-testers]

Hi Tom,

  I'm seeing a lot of test failures, but most importantly, the
test-release.sh script fails to build any binary for both powerpc OSes
(Ubuntu and RHEL). This is using 12.0.0 to build, we're still investigating.

  A quick list of regressions we're seeing:

`libc++ ::
std/numerics/numeric.ops/numeric.ops.midpoint/midpoint.float.pass.cpp`
`libc++ :: libcxx/atomics/atomics.align/align.pass.cpp`.

On RHEL:

compiler-rt/lib/scudo/standalone/tests/ScudoCxxUnitTest-powerpc64le-Test
compiler-rt/lib/scudo/standalone/tests/ScudoCUnitTest-powerpc64le-Test

due to (on Linux RHEL, so this one is weird):

ld.lld: error: unable to find library -latomic

There's this concerning build failure of an open source Google benchmark:

Benchmarks/snappy/src/third_party/benchmark/src/complexity.cc:85:10:
error: variable 'sigma_gn' set but not used
[-Werror,-Wunused-but-set-variable]
  double sigma_gn = 0.0;
         ^
1 error generated.

when it's clearly used in the lines immediately after it:
https://github.com/google/benchmark/blob/bf585a2789e30585b4e3ce6baf11ef2750b54677/src/complexity.cc

We're also seeing other SPEC benchmark failures and some internal benchmark
failures, and finally `test-release.sh` fails:

UNREACHABLE executed at
/home/conanap/upload/rc1/llvm-project/llvm/lib/Target/PowerPC/PPCCTRLoops.cpp:182!
PLEASE submit a bug report to https://bugs.llvm.org/ and include the
crash backtrace, preprocessed source, and associated run script.

The 13.0.0rc1 is built with 12.0.0 here, so I'll try building with 11.0.0
to see if I will encounter some of the same errors (test-release.sh fails
even with 11.0.0 compilers). We're otherwise still investigating the rest
of the errors.

Albion
