clang-format of LLVM StringSwitch not good

[jurahul]

LLVM's StringSwitch is not formatted well by clang-format. See https://discourse.llvm.org/t/issues-with-clang-format-of-llvm-stringswitch/86359

This issue is to investigate if this can be improved when there is a chain on function calls on the same onject.
