Build failure from Microsoft.AspNetCore.Routing.Microbenchmarks (reason: 'AllMeasurements')

[SteveSandersonMS]

Filing as part of buildops.

Build failure: https://dev.azure.com/dnceng-public/public/_build/results?buildId=924728 (see the Windows x64 job)

Error: Microsoft.AspNetCore.Routing.Microbenchmarks.dll -f * --validate-fast" exited with code 1

Possibly due to this preceding issue: 'JumpTableMultipleEntryBenchmark.Dictionary: Dry(Toolchain=InProcessNoEmitToolchain, IterationCount=1, LaunchCount=1, RunStrategy=ColdStart, UnrollFactor=1, WarmupCount=1) [Count=100], 0 runs' failed, reason: 'AllMeasurements'

This clearly appears to be an intermittent failure (it didn't also happen on the previous or next build). However our "intermittent failures" across the whole stack are reaching a critical mass where a large fraction of builds are failing, so I think we'll have no choice but to investigate them or disable problematic components.

@joperezr Does your team own ASP.NET Core routing these days? Or is it still @mkArtak as listed in area owners?

[joperezr]

Yes, we own routing. Added this to the planning project, so we'll take a look.
