With Chapel's use of LLVM, we try to avoid modifying any of the source files that come from the LLVM distribution.  Our own Makefile that builds Chapel also invokes cmake to build LLVM.  I have tried setting environment variables and passing command-line arguments, and nothing seems to work.
Looks like nobody got around adding a flag. (this really should be fixed).

In the meantime `cmake -DCMAKE_CXX_FLAGS="-DLLVM_ENABLE_DUMP"` should do the trick.
