Including Leandro as who seems to maintain the workers - could you take a look
at this? This could help committers from receiving "Buildbot failure in LLVM
Buildbot on" spam.

Empirically it looks like __builtin_operator_new(__args...); needs clang 7.0 or above to compile, at least on Arm and AArch64. The build-bot is using clang 5.01.
It looks like to fix this the compiler on the buildbot will need upgrading or we'll need to retire the buildbot. I have some tickets lodged with an infrastructure team but until they are resolved I suggest ignoring it.
