llvm*: Fix core usage in tests
lit (LLVM Integrated Tester) [0] by default uses as many threads as the build host has cores, ignoring the user's core settings for the build. This passes the configured core count on to lit, along with LLVM's default settings for it which we otherwise override in the process [1].
