Use `lld` as a linker, it is superior to `ld` or `gold`.
It consumes less memory and much faster.
Also, prefer dynamic linking for faster development cycles.

Subject: [cfe-dev] Unusually high ram usage on tests

Hi everyone,
I am running 'ninja check-clang-analysis' on the release build of clang with LLVM_PARALLEL_LINK_JOBS set to 2 and assertions off. I am on Ubuntu 20.04. This is taking up almost 10 gb of memory (6 from ram, 4 from swap). I have been running this command for over a month and I haven't seen this sort of memory usage. Is this normal? Or am I missing something?
Warm regards,
