llvmPackages_15.llvm: run the tests on macOS
there are a few parts to this:
- adding darwin specific check deps
- working around referencing LLVM dylibs during the checkPhase in a
way that supports darwin
+ previously we just set `$LD_LIBRARY_PATH` and/or made some
strategic symlinks
+ now we have LLVM's `lit` config set the appropriate env vars as
needed (as is done for other LLVM subprojects)
+ in retrospect switching to `installCheckPhase` might have been the
better move..
- patching `lit` to deal with `$DYLD_LIBRARY_PATH` being purged for
new "protected" processes
