@dotnet-bot test Ubuntu x64 Formatting please

@dotnet/jit-contrib can one of you help figure out the formatting problem here? I am not familiar with the output of the formatting error and it looks quite strange.

@janvorli download https://ci.dot.net/job/dotnet_coreclr/job/master/job/x64_windows_nt_formatting_prtest/538/artifact/format.patch and run git apply format.patch

[janvorli]
