Planned hostname prefix is linux-arm-aws, with the individual builders having a --nn suffix.

Edit: This builder will also serve as a security trybot. A separate set of instances will be used for that, using linux-arm-aws-security as their hostname prefix.

Change https://go.dev/cl/559158 mentions this issue: main.star: use linux-arm64 cipd_platform dimension for linux-arm host type

@dmitshur @gopherbot
main.star: use linux-arm64 cipd_platform dimension for linux-arm host…
7f2f86e 
… type

The m6g.xlarge instance types are capable of running both 64- and 32-bit
arm binaries, and Swarming Bot reports the cipd_platform dimension as
'linux-arm64'. So update the LUCI dimensions mapping for the linux-arm
builder type accordingly.

Also stop treating linux-arm as a best-effort platform since it doesn't
need to be. There are versions of git and bootstrap-go available for it.
This happens implicitly alongside the cipd_platform value change.

For golang/go#65241.

@dmitshur @gopherbot
main.star: match previous environment in linux-arm builder
ec58d9b 
The coordinator version of this builder is running well and passing,
but my attempts to start up a LUCI version of the same builder so far
are running into frequent stalls and other signs of corruption, and
infrequent successful runs.

Try to zero in on what's causing the difference by first matching the
environment configuration of the previous builder and see if that has
any effect, or if it's something else.

For golang/go#65241.

I have some evidence suggesting that setting GOARM=6 is the load-bearing
piece of configuration, not the other two. Take the next step to collect
more data points and test that hypothesis.

Change https://go.dev/cl/560464 mentions this issue: main.star: update for linux/arm builder reporting its arch as 32-bit arm

@dmitshur @gopherbot
main.star: update for linux/arm builder reporting its arch as 32-bit arm
04f3fd1 
I've realized it's possible to use setarch on an arm64 host and get
it to report its architecture as 32-bit arm. That works, and causes
the Swarming Bot to report its cipd_platform as linux-armv6l, which
should produce a more useful signal for the purpose of coverage for
the linux/arm port.

Update is_fully_supported to say yes for cipd_platform:linux-armv6l.
That is still my intention, it just needs to be done explicitly now.

For golang/go#65241.

A new distinct set of VMs will be used for security
pre-submit and release testing.

We choose not to have a shared pool in the security
environment at this time, so take that into account.

@dmitshur @gopherbot
main.star: unmark the linux-arm builder as having a known issue
1d49083 
The builder has been running some time and producing good signal so far.
Remove its known issue as its next step. The issue tracks the remaining
work to document its setup, and improve life-cycle edge case handling.

Also change the default so that known-issue internal builders start out
as optional. It doesn't make a difference now, but it probably would be
more useful behavior to default to in the future.

For golang/go#65241.
