No particular downsides come to mind, rather upsides:
* Generally no requirement to rebuild Mesa after changes to LLVM.
* Both LLVM and Mesa take significantly less time, memory and disk
space to build.

I'm only aware of such issues with the Steam runtime, which are arguably
because the current implementation (if not the design) of the Steam
runtime is broken (in ways affecting libraries other than Mesa as well,
so it's not like Mesa linking LLVM statically magically solves all Steam
BTW, AFAIK just linking LLVM statically into Mesa isn't enough to avoid
these issues, one would also need to link libstdc++ statically into LLVM.
