Add back fallthrough annotations removed by 7f3afab (#148032)

Browse Source 
The original commit removed them to avoid the dependency on llvm Support
because of LLVM_FALLTHROUGH, but this triggers `-Wimplicit-fallthrough`
warnings.

LLVM requires a C++17 compiler now, so we should be able to use the
standard [[fallthrough]] attribute.
