Sam McCall 4bd6ebb495 clangd: use -j for background index pool ... Summary: clangd supports a -j option to limit the amount of threads to use for parsing TUs. However, when using -background-index (the default in later versions of clangd), the parallelism used by clangd defaults to the hardware_parallelisn, i.e. number of physical cores. On shared hardware environments, with large projects, this can significantly affect performance with no way to tune it down. This change makes the -j parameter apply equally to parsing and background index. It's not perfect, because the total number of threads is 2x the -j value, which may still be unexpected. But at least this change allows users to prevent clangd using all CPU cores.
