This is a follow up patch on #245 and #252
It adds a new builder called clang-arm64-windows-msvc-testsuite. It will
do stage1 and stage2 builds without running checks. Checks are already
covered by single stage and 2 stage bots.

This updates LLVM WoA bots with following changes:
1) Do not run stage1 testing on 2 stage clang bot.
2) Remove redundant workers.
3) Remove -DCOMPILER_RT_BUILD_PROFILE=OFF
4) Add compiler-rt to single stage bot
5) Set clean=False for the 2stage bots
6) Set "-DCLANG_DEFAULT_LINKER=lld" for all WoA bots

Checks are already covered by single stage and 2 stage bots.

What is the reason to not add this onto the 2 stage bots?

I can think of a few:

  • The 2 stage bot takes approximately a human lifetime already :)
  • The results from each bot will match the name (test suite failures from testsuite, stage 1 checks from single stage etc.)

Any more?

Assuming we have the hardware resource I agree with the decision.

I know this is very late to say this, but it is confusing that we have "msvc" in the bot names. Could we change that for this new one? clang-arm64-windows-testsuite would be fine.

A couple of times I've had to explain that the "msvc" bot actually uses clang-cl.

I would have proposed changing all the names but that's a fiddly multi week process so I never had the energy to do it.

Does enabling flang not just automatically do this?

# so, before that's fixed, disable everything that triggers its build.

On Windows on Arm, we are only building compiler-rt for the compiler runtime part, correct? I see that all these are disabling the sanitizers.

Be careful with the timing of when this change lands vs. when you remove the agent from the actual machine. I managed to get our server IP banned because I left some workers running that kept trying to connect to the build master.

If the machine is offline before this lands there should be no problem.

Where are you disabling the check stage 1 and 2 here? Also this doesn't seem to be a 2 stage, there's no useTwoStage.
