Same for PGO pipelines: https://dev.azure.com/dnceng-public/public/_build/results?buildId=29291&view=ms.vss-test-web.build-test-results-tab&runId=589060&resultId=109669&paneView=debug

where it doesn't expect instrumentation in codegen:

__tmp0_Runtime_73681.cs:19:16: error: CHECK-NOT: excluded string found in input
// CHECK-NOT: CORINFO_HELP
^
__jit_disasm.out:31:7: note: found here
call CORINFO_HELP_CLASSPROFILE32
^~~~~~~~~~~~

Input file: __jit_disasm.out
Check file: __tmp0_Runtime_73681.cs

-dump-input=help explains the following input dump.

Outerloop and PGO runs do not show this error in the latest runs. Closing.
